Raphael Isemann a37734f643 [ASTImporter] Prevent the ASTImporter from creating multiple main FileIDs.
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).

Reid Kleckner cd62511496 Remove clang::ast_type_traits namespace in favor of clang
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.

MachineVerifierPass by default on X86 and the fact that

Ben Langmuir 2ac0c4b46e [DirectoryWatcher] Fix misuse of FSEvents API and data race
I observed two bugs in the DirectoryWatcher on macOS

1. We were calling FSEventStreamStop and FSEventStreamInvalidate before
we called FSEventStreamStart and FSEventStreamSetDispatchQueue, if the
DirectoryWatcher was destroyed before the initial async work was done.
This violates the requirements of the FSEvents API.

2. Calls to Receiver could race between the initial work and the
invalidation during destruction.

The second issue is easier to see when using TSan.

mydeveloperday 70c98671fa [clang-format] Add option for not breaking line before ObjC params
Summary:
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) {
        u = c;
    }]
}
```
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.

Martin Probst a324fcf1ae clang-format: insert trailing commas into containers.
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.

Martin Probst 4c9d691445 clang-format: [JS] fix `??` opreator wrapping.
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.

mydeveloperday 14c044756e [clang-format] Add IndentCaseBlocks option
Summary:
The documentation for IndentCaseLabels claimed that the "Switch
statement body is always indented one level more than case labels". This
is technically false for the code block immediately following the label.
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
treats the block as a scope block (which it technically is).

(Note: regenerated ClangFormatStyleOptions.rst using tools/dump_style.py)

Martin Probst 9835cf1590 clang-format: [JS] pragmas for tslint, tsc.
Summary:
tslint and tsc (the TypeScript compiler itself) use comment pragmas of
the style:

  // tslint:disable-next-line:foo
  // @ts-ignore

These must not be wrapped and must stay on their own line, in isolation.
For tslint, this required adding it to the pragma regexp. The comments
starting with `@` are already left alone, but this change adds test
coverage for them.

```
// With Style.PointerAlignment = FormatStyle::PAS_Left:

struct A {

  operator const char *() const { return ""; }

```
The code was checking if the type specifier was directly preceded by `operator`.
However there could be comments and `const/volatile` in between.

Volodymyr Sapsai 83f4c3af02 [modules] Do not cache invalid state for modules that we attempted to load.
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.

Yuanfang Chen 647c3f4e47 [Support] make report_fatal_error `abort` instead of `exit`
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.).

Summary:
Found a bug introduced with BraceWrappingFlags AfterControlStatement MultiLine. This feature conflicts with the existing BeforeCatch and BeforeElse flags.

For example, our team uses BeforeElse.

if (foo ||
    bar) {
  doSomething();
}
else {
  doSomethingElse();
}

If we enable MultiLine (which we'd really love to do) we expect it to work like this:

if (foo ||
    bar)
{
  doSomething();
}
else {
  doSomethingElse();
}

What we actually get is:

if (foo ||
    bar)
{
  doSomething();
}
else
{
  doSomethingElse();
}
