fac2371be3 clang-format: Add support for SEH __try / __except / __finally blocks.
This lets clang-format format

    __try {
    } __except(0) {
    }

and

    __try {
    } __finally {
    }

correctly. __try and __finally are keywords if `LangOpts.MicrosoftExt` is set,
so this turns this on.  This also enables a few other keywords, but it
shouldn't overly perturb regular clang-format operation.  __except is a
context-sensitive keyword, so `AdditionalKeywords` needs to be passed around to
a few more places.

Fixes PR22321.

I have so far not succeeded in finding a nicely reduced test case or an
observable difference which could help me create a test failure without
msan.

ece3d3c26e clang-format: Let Chromium use the Google default for AlignTrailingComments.
r225141 changed the defaults of AllowShortIfStatementsOnASingleLine and
AlignTrailingComments for Google style and added explicit overrides for
Chromium style to undo these changes.  For AllowShortIfStatementsOnASingleLine
that's good as the Android style guide (which Chromium uses for Java) explicitly
permits single-line ifs. But it's silent on trailing comments, to it makes
sense for Chromium style to just follow Google style.

does for C++.

34272657de clang-format: Format extern "C" blocks like namespace blocks.
namespace blocks act as if KeepEmptyLinesAtTheStartOfBlocks is always true,
and aren't collapsed to a single line even if they would fit. Do the same

Before,

  extern "C" {

  void ExternCFunction();

  }

was collapsed into `extern "C" { void ExternCFunction(); }`. Now it stays like
it was.

650ecb53ca Fix bug 20892 - clang-format does not handle C-style comments
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20892

Add support of C-style formatting enabling/disabling directives. Now the following two styles are supported:

  // clang-format on
  /* clang-format on */

The flexibility in comments (support of extra spaces and/or slashes, etc.) is deliberately avoided to simplify search in large code bases.

Before:
  var regex = / a\//; int i;

After:
  var regex = /a\//;

This required pushing the Lexer into its wrapper class and generating a
new one in this specific case. Otherwise, the sequence get lexed as a
//-comment. This is hacky, but I don't know a better way (short of
supporting regex literals in the Lexer).

Pushing the Lexer down seems to make all the call sites simpler.
