clang-format incorrectly splits the `[[` in a long argument list
```
void SomeLongClassName::ALongMethodNameInThatClass([[maybe_unused]] const shared_ptr<ALongTypeName>& argumentNameForThat
LongType) {
}
```
becomes
```
void SomeLongClassName::ALongMethodNameInThatClass([
[maybe_unused]] const shared_ptr<ALongTypeName> &argumentNameForThatLongType) {
}
```
leaving one `[` on the previous line
For a function with just 1 very long argument, clang-format chooses to split between the `[[`,
This revision prevents the slip between the two `[` and the second `[`

Summary: systemd recently added a clang-format file. One issue I
encountered in using clang-format on systemd is that systemd does
not add a space before the parens of their foreach macros but
clang-format always adds a space. This does not seem to be
configurable in clang-format. This revision adds the
ControlStatementsExceptForEachMacros option to SpaceBeforeParens
which puts a space before all control statement parens except
ForEach macros. This drastically reduces the amount of changes
when running clang-format on systemd's source code.

Summary:
Ensure the clang-format unit tests are themselves clang-formatted
Having areas of the llvm code which are clang-format clean, give us more areas to run new clang-format binaries on ensuring we haven't broken anything.
It seems to me we SHOULD have this clang-formatted at a minimum, otherwise how can we expect others to use clang-format if we "don't eat our own dogfood", also if the tests are dependent on the formatting of the code then that would also be bad!

Link to LLVMTestingSupport via target_link_libraries() instead of
clang_target_link_libraries(). The latter is ineffective if tests
are linked to libclang.so. This solution is consistent with what other
tests do.
Summary: The condition added with the new setting checked whether the character was an l-brace, not specifically a lambda l-brace, when deciding whether it was possible to break before it or not. This caused the l-brace of some initialiser lists to break onto the next line with the first argument of the initialiser list when the setting was enabled.

In ImportContext(…) we may call into CompleteDecl(…) which if FromRecrord is not
defined will start the definition of a ToRecord but from what I can tell at least
one of the paths though here don't ensure we complete the definition.
For a RecordDecl this can be problematic since this means we won’t import base

Summary:
Macro argument expansion logic relies on skipping file IDs that created
as a result of an include. Unfortunately it fails to do that for
predefined buffer since it doesn't have a valid insertion location.
As a result of that any file ID created for an include inside the
predefined buffers breaks the traversal logic in
SourceManager::computeMacroArgsCache.
To fix this issue we first record number of created FIDs for predefined
buffer, and then skip them explicitly in source manager.
Another solution would be to just give predefined buffers a valid source
location, but it is unclear where that should be..

Summary:
Even when BreakBeforeBinaryOperators is set, AlignOperands kept
aligning the beginning of the line, even when it could align the
actual operands (e.g. after an assignment).
With this patch, there is an option to actually align the operands, so
that the operator gets right-aligned with the equal sign or return
operator:
int aaaaa = bbbbbb
+ cccccc;
return aaaaaaa
&& bbbbbbb;
This not happen in parentheses, to avoid 'breaking' the indentation:
if (aaaaa
&& bbbbb)
return;

When multiple ternary operators are chained, e.g. like an if/else-if/
else-if/.../else sequence, clang-format will keep aligning the colon
with the question mark, which increases the indent for each
conditionals:
int a = condition1 ? result1
: condition2 ? result2
: condition3 ? result3
: result4;
This patch detects the situation (e.g. conditionals used in false branch
of another conditional), to avoid indenting in that case:
int a = condition1 ? result1
: condition2 ? result2
: condition3 ? result3
: result4;
When BreakBeforeTernaryOperators is false, this will format like this:
int a = condition1 ? result1 :
condition2 ? result2 :
conditino3 ? result3 :
result4;

This patch adds support for importing fixed point literals, following

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
};

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.
