The attempt to fix requoting behavior in r280487 after changes to
tooling::Replacements are incomplete. We essentially need to add to
replacements at the same position, one to insert a line break and one to
change the quoting and that's incompatible with the new
tooling::Replacement API, which does not allow for order-dependent
Replacements. To make the order clear, Replacements::merge() has to be
used, but that requires the merged Replacement to actually refer to the
changed text, which is hard to reproduce for the requoting.
This change fixes the behavior by moving the requoting to a completely
separate pass. The added benefit is that no weird ColumnWidth
calculations are necessary anymore and this should just work even if we
implement string literal splitting in the future.

r257257 change the way clang-format enforces line breaks after a

Differences from the GCC extension:
* __auto_type is also permitted in C++ (but only in places where
it could appear in C), allowing its use in headers that might
be shared across C and C++, or used from C++98
* __auto_type can be combined with a declarator, as with C++ auto
(for instance, "__auto_type *p")
* multiple variables can be declared in a single __auto_type
declaration, with the C++ semantics (the deduced type must be
the same in each case)
This patch also adds a missing restriction on applying typeof to
a bit-field, which GCC has historically rejected in C (due to
lack of clarity as to whether the operand should be promoted).
The same restriction also applies to __auto_type in C (in both
GCC and Clang).

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.

clang accepts both #include and #import for includes (the latter having an
implicit header guard). Let clang-format interleave both types if
--sort-includes is passed. #import is used frequently in Objective-C code.

If a RegExp contains a character group with a quote (/["]/), the
trailing end of it is first tokenized as a string literal, which leads
to the merging code seeing an unbalanced bracket.
This change parses regex literals from the left hand side. That
simplifies the parsing code and also allows correctly handling escapes
and character classes, hopefully correctly parsing all regex literals.
Patch by Martin Probst, thank you.

Slashes in regular expressions do not need to be escaped and do not
terminate the regular expression even without a preceding backslash.

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)

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.

This was made much easier by introducing an IncludeCategory struct to
replace the previously used std::pair.
Also, cleaned up documentation and added examples.

Apart from being cleaner this also means that clang-format no longer has
access to the host file system. This isn't necessary because clang-format
never reads includes :)
Includes minor tweaks and bugfixes found in the VFS implementation while
running clang-format tests.

In versions of clang prior to r238238, __declspec was recognized as a keyword in
all modes. It was then changed to only be enabled when Microsoft or Borland
extensions were enabled (and for CUDA, as a temporary measure). There is a
desire to support __declspec in Playstation code, and possibly other
environments. This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword. Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and
disabled in all other environments.

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.

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.

Recognize the main module header as well as different #include categories.
This should now mimic the behavior of llvm/utils/sort_includes.py as
well as clang-tools-extra/clang-tidy/llvm/IncludeOrderCheck.cpp very
closely.

JavaScript allows keywords to appear in IdenfierName positions, e.g.
fields, or object literal members, but not as plain identifiers.
