Benjamin Kramer 3508c35e85 [clang-format] Use in-class initializers to simplify constructor.
Sadly C++11 doesn't let us use initializers on bitfield members (DR1341). NFC.

Daniel Jasper fa8e4f7676 clang-format: [JS] Hotfix for runtime issue with deeply nested JS code.
I have not succeeded in writing a proper test case for this yet and we
also need to solve the underlying fundamental problem of trying too
many combinations with nested blocks (basically this somewhat works
around our Dijkstra algorithm). Preventing this linebreak is good
anyways as usually the penalties never make us choose it (that's why I
can't create a test) and it also looks ugly.

Also cleaned up state comparison code that I discovered while hunting
this down.

Daniel Jasper 5ec4a06c79 clang-format: Revamp nested block formatting.
This fixed llvm.org/PR21804 and hopefully a few other strange cases.

Before:
    if (blah_blah(whatever, whatever, [] {
      doo_dah();
      doo_dah();
    })) {
    }
    }

After:
    if (blah_blah(whatever, whatever, [] {
          doo_dah();
          doo_dah();
        })) {
    }
    }

Daniel Jasper e167891bd8 clang-format: Refactor indentation behavior for multiple nested blocks.
This fixes a few oddities when formatting multiple nested JavaScript
blocks, e.g.:

Before:
  promise.then(
      function success() {
        doFoo();
        doBar();
      },
      [], function error() {
        doFoo();

      });
  promise.then([],
               function success() {
                 doFoo();
                 doBar();
               },
               function error() {
    doFoo();
    doBaz();
  });

After:
  promise.then(
      function success() {
        doFoo();
        doBar();
      },

      function error() {
        doFoo();
        doBaz();
      });
  promise.then([],
               function success() {
                 doFoo();
                 doBar();
               },
               function error() {

This fixes two issues:
1) The indent of a line comment was not adapted to the subsequent

Daniel Jasper d4a03dbb0b 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).
