4d72449de6 clang-format: Fixed typecast getting put on a separate line from the
key in Obj-C dictionary literals

This fixes: https://llvm.org/PR22647

9cb1ac28b9 clang-format: Fixed missing space between Obj-C for/in and a typecast.
Fixes this bug: https://llvm.org/bugs/show_bug.cgi?id=24504

TokenAnnotator::spaceRequiredBetween was handling TT_ForEachMacro but
not TT_ObjCForIn, so lines that look like:

  for (id nextObject in (NSArray *)myArray)

would incorrectly turn into:

  for (id nextObject in(NSArray *)myArray)

39828256b0 [clang-format] Stop alignment sequences on open braces and parens when
aligning assignments.

This was done correctly when aligning the declarations, but not when
aligning assignments.

FIXME: The code between assignments and declarations alignment is
roughly duplicated and
would benefit from factorization.

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.

Patch by Beren Minor, thank you.

c1bc38ed4f clang-format: Add a new brace style "custom" as well as flags to
control the individual braces. The existing choices for brace wrapping
are now merely presets for the different flags that get expanded upon
calling the reformat function.

All presets have been chose to keep the existing formatting, so there
shouldn't be any difference in formatting behavior.

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++.

Summary:
Add brace style `BS_WebKit` as described on https://www.webkit.org/coding/coding-style.html:

* Function definitions: place each brace on its own line.
* Other braces: place the open brace on the line preceding the code block; place the close brace on its own line.

Set brace style used in `getWebKitStyle()` to the newly added `BS_WebKit`.

b001a0ba5e clang-format: Add MacroBlock{Begin,End} options
The MacroBlockBegin and MacroBlockEnd options make matching macro identifiers
behave like '{' and '}', respectively, in terms of indentation.

Mozilla code, for example, uses several macros that begin and end a scope.
Previously, Clang-Format removed the indentation resulting in:

    MACRO_BEGIN(...)
    MACRO_ENTRY(...)
    MACRO_ENTRY(...)
    MACRO_END

Now, using the options

    MacroBlockBegin: "^[A-Z_]+_BEGIN$"
    MacroBlockEnd: "^[A-Z_]+_END$"

will yield the expected result:

    MACRO_BEGIN(...)
      MACRO_ENTRY(...)
      MACRO_ENTRY(...)

1a02822704 clang-format: Fix child-formatting in macros.
This fixes a case where the column limit was incorrectly calculated
leading to a macro like this:

  #define A                                       \
    [] {                                          \
      xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(        \
          xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx); \
    }

exceeding the column limit.

3d3ea84a4f Refactor clang-format's formatter.
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
   of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
   LineJoiner iterate over the lines so we never operate on a line that might
   be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.

Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
   only the outer expression was affected:
   int x = s({ // clang-format only this line
     class X {
       public:
    // ^ this starts at the non-modified indnent level; previously we would
    //   not fix this, now we correctly outdent it.
       void f();
     };
   });
2. We would incorrectly align comments across lines that do not have comments
   for lines with nested blocks:
   int expression; // with comment
   int x = s({
     int y; // comment
     int z; // we would incorrectly align this comment with the comment on
            // 'expression'
   });

In particular:
* If the difference between the longest and shortest element, we copped
  out of column format completely. Now, we instead allow to arrange
  these in a single column, essentially enforcing a one-per-line format.
* Allow column layout even if there are braced lists. Especially, if
  there are many short lists, this can be beneficial. The bad case,
  where there is a long nested init list is usually caught as we now
  limit the length difference of the longest and shortest element.
