0a589416e8 clang-format: Handle \n the same way as std::endl with stream operator.
clang-format breaks multi-line streams after std::endl.
It now also break for '\n', the suggested replacement for std::endl:

  http://llvm.org/docs/CodingStandards.html#avoid-std-endl

Before:
  llvm::errs() << aaaaaaaaaaaaaaaaaaaaaa << '\n' << bbbbbbbbbbbbbbbbbbbbbb
               << '\n';
  llvm::errs() << aaaa << "aaaaaaaaaaaaaaaaaa\n" << bbbb
               << "bbbbbbbbbbbbbbbbbb\n";

After:
  llvm::errs() << aaaaaaaaaaaaaaaaaaaaaa << '\n'
               << bbbbbbbbbbbbbbbbbbbbbb << '\n';
  llvm::errs() << aaaa << "aaaaaaaaaaaaaaaaaa\n"
               << bbbb << "bbbbbbbbbbbbbbbbbb\n";

This changeset ensure that multiline streams have a line break after:
  - std::endl
  - '\n'
  - "\n"
  - "Some Text\n"

00492f96bf clang-format: Improve line wrapping behavior in call sequences.
r256750 has been leading to an undesired behavior:

  aaaaaaaaaa
      .aaaaaaaaaaaaaaaaaaaaaaaa.aaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

This change increases penalty for wrapping before member accesses that aren't
calls. Thus, this is again formatted as (as it has been before r256750):

  aaaaaaaaaa.aaaaaaaaaaaaaaaaaaaaaaaa.aaaaaa(
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

870d1bcdf9 clang-format: Add test for AlignAfterOpenBracket = AlwaysBreak in C++.
Revision 251405 added AlwaysBreak to support Google's JavaScript style. This
changeset complete existing AlignsAfterOpenBracket tests to exercise
AlwaysBreak for C++.

I thought this would be worthwhile.  With this option we can support request
from http://lists.llvm.org/pipermail/cfe-dev/2015-May/042942.html, that had
been requested a few times. This also partially solve related Bug 23422 and is
probably sufficient for most people.

  AlignAfterOpenBracket = FormatStyle::BAS_AlwaysBreak;
  BinPackArguments = false;
  BinPackParameters = false;

With these setting we obtain this formatting:

  void fooWithAVeryLongParamList(
      int firstParameter,
      int secondParameter
      int lastParameter)
  {
      object.alsoThisDoenstFitSoIBreakImmidiatly(
          firstParameter,

6501f7e8fd clang-format: Add an additional value to AlignAfterOpenBracket: AlwaysBreak.
Summary:
If this option is set, clang-format will always insert a line wrap, e.g.
before the first parameter of a function call unless all parameters fit
on the same line. This obviates the need to make a decision on the
alignment itself.

Use this style for Google's JavaScript style and add some minor tweaks
to correctly handle nested blocks etc. with it. Don't use this option
for for/while loops.

e12597cc23 [clang-format] Add support of consecutive declarations alignment
This allows clang-format to align identifiers in consecutive
declarations. This is useful for increasing the readability of the code
in the same way the alignment of assignations is.

The code is a slightly modified version of the consecutive assignment
alignment code. Currently only the identifiers are aligned, and there is
no support of alignment of the pointer star or reference symbol.

The patch also solve the issue of alignments not being possible due to
the ColumnLimit for both the existing AlignConsecutiveAligments and the
new AlignConsecutiveDeclarations.

c1bc38ed4f clang-format: Add a new brace style "custom" as well as flags to

All presets have been chose to keep the existing formatting, so there

Also change the dump_format_style.py to properly document the nested
structs that are used to keep these flags discoverable among all the
configuration flags.

100ffc632a clang-format: Be more conservative about specially indenting blocks in C++.
This is a bit of a step back of what we did in r222531, as there are
some corner cases in C++, where this kind of formatting is really bad.

Example:
Before:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant = [&]() {
    return true;
  }, aaaaa aaaaaaaaa);

After:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant =
                               [&]() { return true; },
                           aaaaa aaaaaaaaa);

The block formatting logic in JavaScript will probably go some other changes,
too, and we'll potentially be able to make the rules more consistent again. For
now, this seems to be the best approach for C++.
