Roman Kashitsyn 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:

This required pushing the Lexer into its wrapper class and generating a

supporting regex literals in the Lexer).

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

Roman Kashitsyn a043cedf0a Fixes bug 20587 - Add K&R break before braces style
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20587

Added K&R style. It could be enabled by the following option:

```
BreakBeforeBraces: KernighanRitchie
```

This style is like `Attach`, but break *only* before function
declarations.

As I can see, no additional logic required to support this style, any
style different from other styles automagically satisfies K&R.

Alp Toker 0621cb2e7d Make clang's rewrite engine a core feature
The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.

Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.

Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

This patch ensures that the lines of the block comments retain relative

continuation of block comments keep a pointer on the change representing the
whitespace change before the block comment, and a relative column offset to this
change, so that the correct column can be reconstructed at the end of alignment
process.

Manuel Klimek 819788da83 Fix crasher bug.
Due to not resetting the fake rparen data on the token when iterating
over annotated lines, we would pop the last element of the paren stack.

This patch fixes the underlying root cause, and makes the code more
robust against similar problems in the future:
- reset the first token when iterating on the same annotated lines due
  to preprocessor branches
- never pop the last element from the paren stack, so we do not crash,
  but rather incorrectly format
- add assert()s so we can figure out if our assumptions are violated

Alexander Kornienko 4504f93901 Preserve hanging indent when breaking line comments.
Summary:
If we need to break the second line here:
// something: aaaaa aaaaa aaaaaa aaaaa aaaaa
//            aaaaa aaaaa aaaaaa aaaaa aaaaa aaaaa

with the patch it will be turned to

// something: aaaaa aaaaa aaaaaa aaaaa aaaaa
//            aaaaa aaaaa aaaaaa aaaaa aaaaa
//            aaaaa

instead of

// something: aaaaa aaaaa aaaaaa aaaaa aaaaa
//            aaaaa aaaaa aaaaaa aaaaa aaaaa
// aaaaa

Chandler Carruth f8b7266d57 [C++11] Switch the clang-format LLVM style to use C++11 style braced
init list formatting. This suggestion has now gone into the LLVM coding
standards, and is particularly relevant now that we're using C++11.

Updated a really ridiculous number of tests to reflect this change.

Daniel Jasper 5550de684f clang-format: Don't wrap "const" etc. of function declarations.
Generally people seem to prefer wrapping the first function parameter
over wrapping the trailing tokens "const", "override" and "final". This
does not extend to function-like annotations and probably not to other
non-standard annotations.

Before:
  void someLongFunction(int SomeLongParameter)
      const { ... }

After:
  void someLongFunction(
      int SomeLongParameter) const { ... }
