Daniel Jasper 1db6c38687 clang-format: Improve formatting of ObjC array literals.
Before:
  NSArray *arguments =
      @[ kind == kUserTicket ? @"--user-store" : @"--system-store",
         @"--print-tickets", @"--productid", @"com.google.Chrome" ];
After:
  NSArray *arguments = @[
      kind == kUserTicket ? @"--user-store" : @"--system-store",
      @"--print-tickets",
      @"--productid",
      @"com.google.Chrome"
  ];

This fixes llvm.org/PR15231.

Manuel Klimek 71814b4465 Support formatting of preprocessor branches.
We now correctly format:
  void SomeFunction(int param1,
  #ifdef X
                    NoTemplate param2,
  #else
                    template <
  #ifdef A
                        MyType<Some> >
  #else
                        Type1, Type2>
  #endif
                    param2,
  #endif
                    param3) {
    f();
  }

Alexander Kornienko ebb43caae2 Handle zero-width and double-width characters in string literals and comments.
Summary:
Count column width instead of the number of code points. This also
includes correct handling of tabs inside string literals and comments (with an
exception of multiline string literals/comments, where tabs are present before
the first escaped newline).

Daniel Jasper 9fe0e8dacd clang-format: Enable formatting of nested blocks.
Among other things, this enables (better) formatting lambdas and
constructs like:
  MACRO({

        },
        {
          long_statement();

Manuel Klimek 31c85921b2 Fixes various problems with accounting for tabs in the original code.
We now count the original token's column directly when lexing the
tokens, where we already have all knowledge about where lines start.

Before this patch, formatting:
 void f() {
 \tg();
 \th();
 }
would incorrectly count the \t's as 1 character if only the line
containing h() was reformatted, and thus indent h() at offset 1.

Daniel Jasper 8de9ed05b7 clang-format: Add column layout formatting for braced lists
With this patch, braced lists (with more than 3 elements are formatted in a
column layout if possible). E.g.:

  static const uint16_t CallerSavedRegs64Bit[] = {
    X86::RAX, X86::RDX, X86::RCX, X86::RSI, X86::RDI,
    X86::R8,  X86::R9,  X86::R10, X86::R11, 0
  };

Required other changes:
- FormatTokens can now have a special role that contains extra data and can do
  special formattings. A comma separated list is currently the only
  implementation.
- Move penalty calculation entirely into ContinuationIndenter (there was a last
  piece still in UnwrappedLineFormatter).

Daniel Jasper e33d4afa47 clang-format: Add two new style options to support WebKit style.
New options:
* Break before the commas of constructor initializers and align
  the commas with the colon.
* Break before binary operators

Additionally, for styles without column limit, don't just accept
linebreaks done by the user, but instead remove 'invalid' (according
to the current style) linebreaks and add 'required' ones.

Daniel Jasper 8369aa5e12 clang-format: Improve handling of unterminated string literals.

Daniel Jasper b10cbc45ad Add experimental flag for adaptive parameter bin-packing.
This is not activated for any style, might change or go away
completely.

For those that want to play around with it, set
ExperimentalAutoDetectBinPacking to true.

clang-format will then:
Look at whether function calls/declarations/definitions are currently
formatted with one parameter per line (on a case-by-case basis). If so,
clang-format will avoid bin-packing the parameters. If all parameters
are on one line (thus that line is "inconclusive"), clang-format will
make the choice dependent on whether there are other bin-packed
calls/declarations in the same file.

The reason for this change is that bin-packing in some situations can be
really bad and an author might opt to put one parameter on each line. If
the author does that, he might want clang-format not to mess with that.
If the author is unhappy with the one-per-line formatting, clang-format
can easily be convinced to bin-pack by putting any two parameters on the
same line.

* Surround the "->" with spaces.
* Break before "->".

Also fix typo.

                           // comment 1 (Forcing intersting break)
                           param1, param2,
                           // comment 2
                           param3, param4
             });
After:
someFunction(OtherParam, BracedList{
                           // comment 1 (Forcing intersting break)
                           param1, param2,

                           param3, param4
                         });

To do so, the UnwrappedLineParser now stores the information about the
kind of brace in the FormatToken.

Alexander Kornienko ffcc010767 UTF-8 support for clang-format.
Summary:
Detect if the file is valid UTF-8, and if this is the case, count code
points instead of just using number of bytes in all (hopefully) places, where
number of columns is needed. In particular, use the new
FormatToken.CodePointCount instead of TokenLength where appropriate.
Changed BreakableToken implementations to respect utf-8 character boundaries
when in utf-8 mode.
