Martin Probst 3d4a6037ff clang-format: [JS] do not merge imports and exports.
Previously, clang-format would erroneously merge import and export
statements. These need to be kept separate, as the semantics differ.

This patch implements the copy assignment for `CompilerInvocation`.

Eventually, the deep-copy operation will be moved into a `clone()` method (D100460), but until then, this is necessary for basic ergonomics.

Stephen Kelly dd68942f1d [AST] Add TypeLoc support to node introspection
Extend the matchers gathering API for types to record template
parameters.  The TypeLoc type hierarchy has some types which are
templates used in CRTP such as PointerLikeTypeLoc.  Record the inherited
template and template arguments of types inheriting those CRTP types in
the ClassInheritance map.  Because the name inherited from is now
computed, the value type in that map changes from StringRef to
std::string.  This also causes the toJSON override signature used to
serialize that map to change.

Remove the logic for skipping over empty ClassData instances.  Several
classes such as TypeOfExprTypeLoc inherit a CRTP class which provides
interesting locations though the derived class does not.  Record it as a
class to make the locations it inherits available.

Record the typeSourceInfo accessors too as they provide access to
TypeLocs in many classes.

The existing unit tests use UnorderedElementsAre to compare the
introspection result with the expected result.  Our current
implementation of google mock (in gmock-generated-matchers.h) is limited
to support for comparing a container of 10 elements.  As we are now
returning more than 10 results for one of the introspection tests,
change it to instead compare against an ordered vector of pairs.

Because a macro is used to generate API strings and API calls, disable
clang-format in blocks of expected results.  Otherwise clang-format
would insert whitespaces which would then be compared against the
introspected strings and fail the test.

Introduce a recursion guard in the generated code.  The TypeLoc class
has IgnoreParens() API which by default returns itself, so it would
otherwise recurse infinitely.

Stephen Kelly ebc6608fb7 [AST] Remove args from LocationCall
This class initially had args to be generic to future needs. In
particular, I thought that source location introspection should show the
getBeginLoc of CallExpr args and the getArgLoc of
TemplateSpecializationLocInfo etc.  However, that is probably best left
out of source location introspection because it involves node traversal.

If something like this is needed in the future, it can be added in the
future.

Ben Langmuir 93c87fc06e [index] Improve macro indexing support
The major change here is to index macro occurrences in more places than
before, specifically

* In non-expansion references such as `#if`, `#ifdef`, etc.
* When the macro is a reference to a builtin macro such as __LINE__.
* When using the preprocessor state instead of callbacks, we now include
  all definition locations and undefinitions instead of just the latest
  one (which may also have had the wrong location previously).
* When indexing an existing module file (.pcm), we now include module
  macros, and we no longer report unrelated preprocessor macros during
  indexing the module, which could have caused duplication.

Additionally, we now correctly obey the system symbol filter for macros,
so by default in system headers only definition/undefinition occurrences
are reported, but it can be configured to report references as well if
desired.

Extends FileIndexRecord to support occurrences of macros. Since the
design of this type is to keep a single list of entities organized by
source location, we incorporate macros into the existing DeclOccurrence
struct.

Martin Probst 2b30bd2be0 clang-format: [JS] do not collapse - - to --.
In JavaScript, `- -1;` is legal syntax, the language allows unary minus.
However the two tokens must not collapse together: `--1` is prefix
decrement, i.e. different syntax.

Before:

    - -1; ==> --1;

After:

    - -1; ==> - -1;

This change makes no attempt to format this "nicely", given by all
likelihood this represents a programming mistake by the user, or odd
generated code.

The check is not guarded by language: this appears to be a problem in
Java as well, and will also be beneficial when formatting syntactically

Utkarsh Saxena aa979084df [clang][Syntax] Optimize expandedTokens for token ranges.
`expandedTokens(SourceRange)` used to do a binary search to get the
expanded tokens belonging to a source range. Each binary search uses
`isBeforeInTranslationUnit` to order two source locations. This is
inherently very slow.
By profiling clangd we found out that users like clangd::SelectionTree
spend 95% of time in `isBeforeInTranslationUnit`. Also it is worth
noting that users of `expandedTokens(SourceRange)` majorly use ranges
provided by AST to query this funciton. The ranges provided by AST are
token ranges (starting at the beginning of a token and ending at the
beginning of another token).

Therefore we can avoid the binary search in majority of the cases by
maintaining an index of ExpandedToken by their SourceLocations. We still
do binary search for ranges which are not token ranges but such
instances are quite low.

Performance:

Janusz Nykiel e030ce3ec7 [Tooling] Handle compilation databases containing commands with double dashes
As of CMake commit https://gitlab.kitware.com/cmake/cmake/-/commit/d993ebd4,
which first appeared in CMake 3.19.x series, in the compile commands for
clang-cl, CMake puts `--` before the input file. When operating on such a
database, the `InterpolatingCompilationDatabase` - specifically, the
`TransferableCommand` constructor - does not recognize that pattern and so, does
not strip the input, or the double dash when 'transferring' the compile command.
This results in a incorrect compile command - with the double dash and old input
file left in, and the language options and new input file appended after them,
where they're all treated as inputs, including the language version option.

Test files for some tests have names similar enough to be matched to commands
from the database, e.g.:

`.../path-mappings.test.tmp/server/bar.cpp`

can be matched to:

`.../Driver/ToolChains/BareMetal.cpp`

etc. When that happens, the tool being tested tries to use the matched, and
incorrectly 'transferred' compile command, and fails, reporting errors similar
to:

`error: no such file or directory: '/std:c++14'; did you mean '/std:c++14'? [clang-diagnostic-error]`

This happens in at least 4 tests:

  Clang Tools :: clang-tidy/checkers/performance-trivially-destructible.cpp
  Clangd :: check-fail.test
  Clangd :: check.test
  Clangd :: path-mappings.test

The fix for `TransferableCommand` removes the `--` and everything after it when
determining the arguments that apply to the new file. `--` is inserted in the
'transferred' command if the new file name starts with `-` and when operating in
clang-cl mode, also `/`. Additionally, other places in the code known to do
argument adjustment without accounting for the `--` and causing the tests to
fail are fixed as well.

Raphael Isemann e421a74108 [ASTImporter] Fix import of ObjCPropertyDecl that share the same name
Objective-C apparently allows name conflicts between instance and class
properties, so this is valid code:

```
@protocol DupProp
@property (class, readonly) int prop;
@property (readonly) int prop;
@end
```

The ASTImporter however isn't aware of this and will consider the two properties
as if they are the same property because it just compares their name and types.
This causes that when importing both properties we only end up with one property
(whatever is imported first from what I can see).

Beside generating a different AST this also leads to a bunch of asserts and
crashes as we still correctly import the two different getters for both
properties (the import code for methods does the correct check where it
differentiated between instance and class methods). As one of the setters will
not have its associated ObjCPropertyDecl imported, any call to
`ObjCMethodDecl::findPropertyDecl` will just lead to an assert or crash.

This patch introduces a language option to identify host executions

-fno-sycl become driver-only options that are rejected when passed to
-cc1. This is because the frontend and beyond should be looking at
whether the user is doing a device or host compilation specifically.
Because the frontend should only ever be in one mode or the other,
-fsycl-is-device and -fsycl-is-host are mutually exclusive options.
