Summary:
I think we would be better off with tests explicitly specifying the
language mode. Right now Lang_C means C99, but reads as "any C version",
or as "unspecified C version".
I also changed '-std=c++98' to '-std=c++03' because they are aliases (so
there is no difference in practice), because Clang implements C++03
rules in practice, and because 03 makes a nice sortable progression
between 03, 11, 14, 17, 20.

I have seen this myself many times.. if you have format on save and you work in an editor where you are constantly saving (:w muscle memory)
If you are in the middle of editing and somehow you've missed a { or } in your code, somewhere, often way below where you are at the bottom of your file the namespace comment fixer will have put the namespace on the previous closing brace.
This leads to you having to fix up the bottom of the file.
This revision prevents that happening by performing an initial pass of the tokens and simply counting the number of `{` and `}` and ensuring they balance.
If they don't balance we don't do any namespace fixing as it will likely be unstable and incorrect.

Summary:
Declaring these helpers in the ast_matcher namespace in the clangAST
unit test seems inappropriate -- neither these helpers, nor clangAST have
anything to do with AST matchers. Therefore, I moved these helpers to
the clang namespace.
Declaring another typedef called "ArgVector" is not a good idea -- we
already have both "ArgVector", "ArgsVector", and "ArgList". I expanded
it into the underlying type.
Declaring another enum called "Language" is not a good idea because we
arleady have the "clang::Language" enum. I renamed it to
"TestLanguage".
Similarly, I renamed "getBasicRunOptionsForLanguage" to
"getCommandLineArgsForTesting" to explain the semantics better (what are
"run options"?) and not repeat types in the function name
("ForLanguage").

Summary:
The following revision follows D80115 since @MyDeveloperDay and I apparently both had the same idea at the same time, for https://bugs.llvm.org/show_bug.cgi?id=45816 and my efforts on tooling support for AMDVLK, respectively.
This option aligns adjacent bitfield separators across lines, in a manner similar to AlignConsecutiveAssignments and friends.
Example:
```
struct RawFloat {
uint32_t sign : 1;
uint32_t exponent : 8;
uint32_t mantissa : 23;
};
```
would become
```
struct RawFloat {
uint32_t sign : 1;
uint32_t exponent : 8;
uint32_t mantissa : 23;
};
```
This also handles c++2a style bitfield-initializers with AlignConsecutiveAssignments.
```
struct RawFloat {
uint32_t sign : 1 = 0;
uint32_t exponent : 8 = 127;
uint32_t mantissa : 23 = 0;
}; // defaults to 1.0f
```
Things this change does not do:
- Align multiple comma-chained bitfield variables. None of the other
AlignConsecutive* options seem to implement that either.
- Detect bitfields that have a width specified with something other
than a numeric literal (ie, `int a : SOME_MACRO;`). That'd be fairly
difficult to parse and is rare.

to see if the FileEntry is the main file without calling translateFile, but by using the new
isMainFile check instead. This speeds up preamble building by 1.5-2x for certain test cases that we have.

Summary:
Currently the 'AlignConsecutive*' options incorrectly align across
elif and else statements, even if they are very far away and across
unrelated preprocessor macros.
This failed since on preprocessor run 2+, there is not enough context
about the #ifdefs to actually differentiate one block from another,
causing them to align across different blocks or even large sections of
the file.
Eg, with AlignConsecutiveAssignments:
```
\#if FOO // Run 1
\#else // Run 1
int a = 1; // Run 2, wrong
\#endif // Run 1
\#if FOO // Run 1
\#else // Run 1
int bar = 1; // Run 2
\#endif // Run 1
```
is read as
```
int a = 1; // Run 2, wrong
int bar = 1; // Run 2
```
The approach taken to fix this was to add a new flag to Token that
forces breaking alignment across groups of lines (MustBreakAlignBefore)
in a similar manner to the existing flag that forces a line break
(MustBreakBefore). This flag is set for the first Token after a
preprocessor statement or diff conflict marker.

Summary:
clang-format currently puts the first enumerator on the same line as the
enum keyword and opening brace if it fits (for example, for anonymous
enums if IndentWidth is 8):
$ echo "enum { RED, GREEN, BLUE };" | clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
enum { RED,
GREEN,
BLUE };
This doesn't seem to be intentional, as I can't find any style guide that
suggests wrapping enums this way. Always force the enumerator to be on a new
line, which gets us the desired result:
$ echo "enum { RED, GREEN, BLUE };" | ./bin/clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
enum {
RED,
GREEN,
BLUE
};
Test Plan:
New test added. Confirmed test failed without change and passed with change by
running:
$ ninja FormatTests && ./tools/clang/unittests/Format/FormatTests

This reverts commit 97aa593a83 as it
causes problems (PR45453) https://reviews.llvm.org/D77574#1966321.
This additionally adds an explicit reference to FrontendOpenMP to
clang-tidy where ASTMatchers is used.
This is hopefully just a temporary solution. The dependence on
`FrontendOpenMP` from `ASTMatchers` should be handled by CMake
implicitly, not us explicitly.

Same restrictions apply as in the other direction: macro arguments are
not supported yet, only full macro expansions can be mapped.

Summary:
Our previous definition of "top-level" was too informal, and didn't
allow for overlapping macros that each directly produce expanded tokens.

Summary:
While [the original diff](https://reviews.llvm.org/D42493) makes a lot of sense, and multiple inline block parameter/trailing paramemter after inline block paramemter should be discouraged, the formatting result is different than what xcode does by default
For the exact same example provided in the original diff:
```
[object
blockArgument:^{
a = 42;
}
anotherArg:42];
```
The code is hard to read and not very visually pleasing
This diff uses `ObjCBreakBeforeNestedBlockParam` to shield from the formatting
When it's set to false, don't allign the inline block paramemters.

Summary:
This adds support for giving hints when using dynamic matchers with enum args. Take this query, I couldn't figure out why the matcher wasn't working:
(Turns out it needed to be "IntegralToBoolean", but thats another bug itself)
```
clang-query> match implicitCastExpr(hasCastKind("CK_IntegralToBoolean"))
1:1: Error parsing argument 1 for matcher implicitCastExpr.
1:18: Error building matcher hasCastKind.
1:30: Incorrect type for arg 1. (Expected = string) != (Actual = String)
```
With this patch the new behaviour looks like this:
```
clang-query> match implicitCastExpr(hasCastKind("CK_IntegralToBoolean"))
1:1: Error parsing argument 1 for matcher implicitCastExpr.
1:18: Error building matcher hasCastKind.
1:30: Unknown value 'CK_IntegralToBoolean' for arg 1; did you mean 'IntegralToBoolean'
```
There are no test cases for this yet as there simply isn't any infrastructure for testing errors reported when parsing args that I can see.

Summary:
The previous change in https://reviews.llvm.org/D77311 attempted to
detect more C++ keywords. However it also precisely detected all
JavaScript keywords. That's generally correct, but many JavaScripy
keywords, e.g. `get`, are so-called pseudo-keywords. They can be used in
positions where a keyword would never be legal, e.g. in a dotted
expression:
x.type; // type is a pseudo-keyword, but can be used here.
x.get; // same for get etc.
This change introduces an additional parameter to
`IsJavaScriptIdentifier`, allowing clients to toggle whether they want
to allow `IdentifierName` tokens, i.e. pseudo-keywords.

Move the listing of allowed clauses per OpenMP directive to the new
macro file in `llvm/Frontend/OpenMP`. Also, use a single generic macro
that specifies the directive and one allowed clause explicitly instead
of a dedicated macro per directive.
We save 800 loc and boilerplate for all new directives/clauses with no
functional change. We also need to include the macro file only once and
not once per directive.
Depends on D77112.

Summary:
C++ defines a number of keywords that are regular identifiers in
JavaScript, e.g. `concept`:
const concept = 1; // legit JS
This change expands the existing `IsJavaScriptIdentifier(Tok)` function
to return false for C++ keywords that aren't keywords in JS.
