Summary:
This revision adds matchers that match calls to the gtest EXPECT and ASSERT
macros almost like function calls. The matchers are placed in separate files
(GtestMatchers...), because they are specific to the gtest library.

Summary:
When importing the main FileID the ASTImporter currently gives it no include location. This means
that any SourceLocations produced for this FileID look to Clang as if they are coming from the
main FileID (as the main FileID has no include location).
Clang seems to expect that there is only one main FileID in one translation unit (which makes sense
during normal compilation), so this behavior leads to several problems when producing diagnostics,
one being that when calling `SourceManager::isBeforeInTranslationUnit` on two SourceLocations
that come from two different ASTContext instances, Clang fails to sort the SourceLocations as
the include chains of the FileIDs don't end up in a single FileID. This causes that Clang crashes
with "Unsortable locations found" in this function.
This patch gives any imported main FileIDs the main FileID of the To ASTContext as its include
location. This allows Clang to sort all imported SourceLocations as now all include chains point
to the main FileID of the To ASTContext. The exact include location is currently set to the start
of the To main file (just because that should always be a valid SourceLocation).

DynTypedNode and ASTNodeKind are implemented as part of the clang AST
library, which uses the main clang namespace. There doesn't seem to be a
need for this extra level of namespacing.
I left behind aliases in the ast_type_traits namespace for out of tree
clients of these APIs. To provide aliases for the enumerators, I used
this pattern:
namespace ast_type_traits {
constexpr TraversalKind TK_AsIs = ::clang::TK_AsIs;
}
I think the typedefs will be useful for migration, but we might be able
to drop these enumerator aliases.

From `clang-format` version 3.7.0 and up, , there is no way to keep following format of ObjectiveC block:
```
- (void)_aMethod
{
[self.test1 t:self w:self callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {

}
```
Regardless of the change in `.clang-format` configuration file, all parameters will be lined up so that colons will be on the same column, like following:
```
- (void)_aMethod
{
[self.test1 t:self
w:self
callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
u = c;
}]
}
```
Considering with ObjectiveC, the first code style is cleaner & more readable for some people, I've added a config option: `ObjCDontBreakBeforeNestedBlockParam` (boolean) so that if it is enable, the first code style will be favored.

Summary:
This change adds an option to insert trailing commas into container
literals. For example, in JavaScript:
const x = [
a,
b,
^~~~~ inserted if missing.
]
This is implemented as a seperate post-processing pass after formatting
(because formatting might change whether the container literal does or
does not wrap). This keeps the code relatively simple and orthogonal,
though it has the notable drawback that the newly inserted comma is not
taken into account for formatting decisions (e.g. it might exceed the 80
char limit). To avoid exceeding the ColumnLimit, a comma is only
inserted if it fits into the limit.
Trailing comma insertion conceptually conflicts with argument
bin-packing: inserting a comma disables bin-packing, so we cannot do
both. clang-format rejects FormatStyle configurations that do both with
this change.

Summary:
clang-format currently treats the nullish coalescing operator `??` like
the ternary operator. That causes multiple nullish terms to be each
indented relative to the last `??`, as they would in a ternary.
The `??` operator is often used in chains though, and as such more
similar to other binary operators, such as `||`. So to fix the indent,
set its token type to `||`, so it inherits the same treatment.
This opens up the question of operator precedence. However, `??` is
required to be parenthesized when mixed with `||` and `&&`, so this is
not a problem that can come up in syntactically legal code.

Its closing bracket aligns with the start of the label.
If the case label are not indented, it leads to a style where the
closing bracket of the block aligns with the closing bracket of the
switch statement, which can be hard to parse.
This change introduces a new option, IndentCaseBlocks, which when true

Partially reverts 0a2be46cfd as it turned
out to cause redundant module rebuilds in multi-process incremental builds.
When a module was getting out of date, all compilation processes started at the
same time were marking it as `ToBuild`. So each process was building the same
module instead of checking if it was built by someone else and using that
result. In addition to the work duplication, contention on the same .pcm file
wasn't making builds faster.
Note that for a single-process build this change would cause redundant module
reads and validations. But reading a module is faster than building it and
multi-process builds are more common than single-process. So I'm willing to
make such a trade-off.

Summary:
This patch could be treated as a rebase of D33960. It also fixes PR35547.
A fix for `llvm/test/Other/close-stderr.ll` is proposed in D68164. Seems
the consensus is that the test is passing by chance and I'm not
sure how important it is for us. So it is removed like in D33960 for now.
The rest of the test fixes are just adding `--crash` flag to `not` tool.
** The reason it fixes PR35547 is
`exit` does cleanup including calling class destructor whereas `abort`
does not do any cleanup. In multithreading environment such as ThinLTO or JIT,
threads may share states which mostly are ManagedStatic<>. If faulting thread
tearing down a class when another thread is using it, there are chances of
memory corruption. This is bad 1. It will stop error reporting like pretty
stack printer; 2. The memory corruption is distracting and nondeterministic in
terms of error message, and corruption type (depending one the timing, it
could be double free, heap free after use, etc.).

This is both more efficient and avoids corner cases in
`SourceManager::isBeforeInTranslationUnit`.
The change is trivial and clearly a performance improvement on the hot
path of building the syntax tree, so sending without review.
Summary:
This patch adds facilities to mutate the syntax trees and produce
corresponding text replacements.
The public interface of the syntax library now includes facilities to:
1. perform type-safe modifications of syntax trees,
2. compute textual replacements to apply the modifications,
3. create syntax trees not backed by the source code.
For each of the three, we only add a few example transformations in this
patch to illustrate the idea, support for more kinds of nodes and
transformations will be done in follow-up patches.
The high-level mutation operations are implemented on top of operations
that allow to arbitrarily change the trees. They are considered to be
implementation details and are not available to the users of the
library.

Patch by Jonathan Thomas (jonathoma)!
Summary:
The exclusive-claim model is successful at resolving conflicts over tokens
between parent/child or siblings. However claims at the spelled-token
level do the wrong thing for macro expansions, where siblings can be
equally associated with the macro invocation.
Moreover, any model that only uses the endpoints in a range can fail when
a macro invocation occurs inside the node.
To address this, we use the existing TokenBuffer in more depth.
Claims are expressed in terms of expanded tokens, so there is no need to worry
about macros, includes etc.
Once we know which expanded tokens were claimed, they are mapped onto
spelled tokens for hit-testing.
This mapping is fairly flexible, currently the handling of macros is
pretty simple (map macro args onto spellings, other macro expansions onto the
macro name token).
This mapping is in principle token-by-token for correctness (though
there's some batching for performance).
The aggregation of the selection enum is now more principled as we need to be
able to aggregate several hit-test results together.
For simplicity i removed the ability to determine selectedness of TUDecl.
(That was originally implemented in 90a5bf92ff97b1, but doesn't seem to be very
important or worth the complexity any longer).
The expandedTokens(SourceLocation) helper could be added locally, but seems to
make sense on TokenBuffer.

Summary:
Also remove the temporary TopLevelDeclaration node and add
UnknownDeclaration to represent other unknown nodes.
See the follow-up change for building more top-level declarations.
Adding declarators is also pretty involved and will be done in another
follow-up patch.

Skip distro detection when we're not running on Linux, or when the target triple is not Linux. This saves a few OS calls for each invocation of clang.exe.
Differential Revision: https://reviews.llvm.org/D70467
Summary:
Adds combinators `maybeDeref` and `maybeAddressOf` to provide a uniform way to handle
nodes which may be bound to either a pointer or a value (most often in the
context of member expressions). Such polymorphism is already supported by
`access`; these combinators extend it to more general uses.

With updates to various LLVM tools that use SpecialCastList.
It was tempting to use RealFileSystem as the default, but that makes it
too easy to accidentally forget passing VFS in clang code.
Summary:
This is a follow-up to 590f279c45, which
moved some of the callers to use VFS.
It turned out more code in Driver calls into real filesystem APIs and
also needs an update.

Line ending detection is now set with the `DeriveLineEnding` option.
CRLF can now be used as the default line ending by setting `UseCRLF`.
When line ending detection is disabled, all line endings are converted
according to the `UseCRLF` option.

Summary:
By additional regex match, grouping of main include can be enabled in files that are not normally considered as a C/C++ source code.
For example, this might be useful in templated code, where template implementations are being held in *Impl.hpp files.
On the occassion, 'assume-filename' option description was reworded as it was misleading. It has nothing to do with `style=file` option and it does not influence sourced style filename.

Summary:
This revision introduces a new interface `MatchComputation` which generalizes
the `Stencil` interface and replaces the `std::function` interface of
`MatchConsumer`. With this revision, `Stencil` (as an abstraction) becomes just
one collection of implementations of
`MatchComputation<std::string>`. Correspondingly, we remove the `Stencil` class
entirely in favor of a simple type alias, deprecate `MatchConsumer` and change
all functions that accepted `MatchConsumer<std::string>` to use
`MatchComputation<std::string>` instead.

Differential Revision: https://reviews.llvm.org/D69896
Summary:
Currently, stencils are defined as a sequence of `StencilParts`. This
differentiation adds an unneeded layer of complexity to the definition of
Stencils. This change significantly simplifies the type structure: a stencil is
now conceptually any object implementing `StencilInterface` and `Stencil` is
just a thin wrapper for pointers to this interface.
To account for the sequencing that was supported by the old `Stencil` type, we
introduce a sequencing class that implements `StencilInterface`. That is,
sequences are just another kind of Stencil and no longer have any special
status.
Corresponding to this change in the type structure, we change the way `cat` is
used (and defined). `cat` bundles multiple features: it builds a stencil from a
sequence of subcomponents and admits multiple different types for its arguments,
while coercing them into the right type. Previously, `cat` was also used to
coerce a single `StencilPart` into a `Stencil`. With that distinction gone, many
uses of `cat` (e.g. in the tests) are unnecessary and have, therefore, been
removed.

Summary:
Most of the statements mirror the ones provided by clang AST.
Major differences are:
- expressions are wrapped into 'ExpressionStatement' instead of being
a subclass of statement,
- semicolons are always consumed by the leaf expressions (return,
expression satement, etc),
- some clang statements are not handled yet, we wrap those into an
UnknownStatement class, which is not present in clang.
We also define an 'Expression' and 'UnknownExpression' classes in order
to produce 'ExpressionStatement' where needed. The actual implementation
of expressions is not yet ready, it will follow later.
