Björn Schäpers 41a09a07ce [clang-format][NFCish] Alphabetical sort Format.(h|pp)
I've:
- Sorted the members of FormatStyle alphabetical. The enums and structs
  are kept close to the member.
- Sorted the yaml io functions, based on the type they operate on.
- Sorted the initializers in getLLVMStyle(), except that penalities are
  kept at the end.
- Sorted the io of FormatStyle, this changes the --dump-config behavior.
- Moved the deprecated options into the only input case, this also
  changes --dump-config, it does not put the not directly used options
  in the .clang-format anymore.
- Sorted the comparisons in operator==.
- Added WhiteSpaceMacros in operator==, I've not actively looked if all
  other members are compared.
- This showed flawed tests (or in my opinion a flawed io operation, but
  that is another discussion and change).

Björn Schäpers cdbe296853 [clang-format] Fix lambda formatting in conditional
Without the patch UnwrappedLineFormatter::analyzeSolutionSpace just ran
out of possible formattings and would put everything just on one line.
The problem was that the the line break was forbidden, but putting the

sstwcw d5be1550f1 [clang-format] Don't crash on malformed preprocessor conditions
Previously the program would crash on this input:

```
#else
#if X
```

The problem was that in `parsePPElse`, `PPBranchLevel` would be
incremented when the first `#else` gets parsed, but `PPLevelBranchCount`
and `PPLevelBranchIndex` would not be updated together.

I found the problem when working on D135740.

[clang-format] Mark pragma region lines as StringLiterals
In our code-base we auto-generate pragma regions the regions
look like method signatures like:

`#pragma region MYREGION(Foo: bar)`

The problem here was that the rest of the line after region
was not marked as stringliteral as in the case of pragma mark
so clang-format tried to change the formatting based on the
method signature.

Added test and mark it similar as pragma mark.

Joseph Huber 037669de8b [clang-format] Do not parse certain characters in pragma directives
Currently, we parse lines inside of a compiler `#pragma` the same way we
parse any other line. This is fine for some cases, like separating
expressions and adding proper spacing, but in others it causes some poor
results from miscategorizing some tokens.

For example, the OpenMP offloading uses certain clauses that contain
special characters like `map(tofrom : A[0:N])`. This will be formatted
poorly as it will be split between lines on the first colon.
Additionally the subscript notation will lead to poor spacing. This can
be seen in the OpenMP tests as the automatic clang formatting with
inevitably ruin the formatting.

For example, the following contrived example will be formatted poorly.
```
#pragma omp target teams distribute collapse(2) map(to: A[0 : M * K])  \
    map(to: B[0:K * N]) map(tofrom:C[0:M*N]) firstprivate(Alpha) \
    firstprivate(Beta) firstprivate(X) firstprivate(D) firstprivate(Y) \
    firstprivate(E) firstprivate(Z) firstprivate(F)
```
This results in this when formatted, which is far from ideal.
```
#pragma omp target teams distribute collapse(2) map(to                         \
                                                    : A [0:M * K])             \
    map(to                                                                     \
        : B [0:K * N]) map(tofrom                                              \
                           : C [0:M * N]) firstprivate(Alpha)                  \
        firstprivate(Beta) firstprivate(X) firstprivate(D) firstprivate(Y)     \
            firstprivate(E) firstprivate(Z) firstprivate(F)
```

This patch seeks to improve this by adding extra logic where the parsing goes
awry. This is primarily caused by the colon being parsed as an inline-asm
directive and the brackes an objective-C expressions. Also the line gets
indented every single time the line is dropped.

This doesn't implement true parsing handling for OpenMP statements.

[clang-format] Correctly annotate star/amp in function pointer params
Inside the arguments part of a function pointer declaration,
`determineStarAmpUsage` results in a binary operator rather than
pointers, because said parens are assumed to be an expression.

This patch correctly marks the argument parens of a function
pointer type as not an expression. Note that this fix already
existed for Objective-C blocks as part of f1f267b447.
As Objective-C blocks and C/C++ function pointers share a lot
of the same logic, that fix also makes sense here.

[clang-format] Correctly indent closing brace of compound requires
When a compound requirement is too long to fit onto a single line, the
braces are split apart onto separate lines, and the contained expression
is indented. However, this indentation would also apply to the closing
brace and the trailing return type requirement thereof.
This was because the indentation level was being restored after all
trailing things were already read

With this change, the initial level of the opening brace is set before
attempting to read any trailing return type requirements

mitchell c0779756a0 [clang-format] Fix alignment in #else preprocessor blocks
Summary:
clang-format makes multiple passes when #if/#else preprocessor blocks are found.  It will make
one pass for normal code and code in the #if block, and then it will make another pass for just
the code in #else blocks. This often results in invalid alignment inside the else blocks because
they do not have any scope or indentAndNestingLevel context from their surrounding tokens/lines.

This patch remedies that by caching any initial indentAndNestingLevel from a second pass and
not breaking/returning early when a scope change is detected.

Fixes #36070

Previously, when an UnwrappedLine began with a hash in a macro
definition, the program incorrectly assumed the line was a preprocessor
directive.  It should be stringification.

The rule in spaceRequiredBefore was added in 8b5297117b.  Its purpose is
to add a space in an include directive.  It also added a space to a
template opener when the line began with a stringification hash.  So we
changed it.

Previously, the heuristic was simply to look for template argument-
specific keywords, such as typename, class, template and auto

This changes the heuristic to instead look for a left angle bracket <

grammar, the template arguments must *directly* follow the introducer.
(This sort of check might just end up being *too* aggressive)
