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.

Since the attribute documentation is now auto-generated, the previous references
are no longer valid. This prevented the docs build from completing
successfully.

-assume-filename, -fallback-style, and -sort-includes are new. (They're also
longer than the previous options, so all descriptions shift over by some amount,
making this diff look larger than it is.)
It looks like someone renamed "General options" to "Generic Options" too.

There's been some changes to the text encoding for sample profiles. This
updates the documentation and an example.

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

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.

While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.
This now allows us to write a matcher like:
varDecl(hasType(namedDecl(hasName("Foo"))))
that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

This flag causes the compiler to emit bit set entries for functions as well
as runtime bitset checks at indirect call sites. Depends on the new function
bitset mechanism.

This patch depends on r246688 (D12341).
The goal is to make LLVM generate different code for these functions for a target that
has cheap branches (see PR23827 for more details):
int foo();
int normal(int x, int y, int z) {
if (x != 0 && y != 0) return foo();
return 1;
}
int crazy(int x, int y) {
if (__builtin_unpredictable(x != 0 && y != 0)) return foo();
return 1;
}

to enable the use of external type references in the debug info
(a.k.a. module debugging).
The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.

Fix a bug in the matcher docs where callExpr(on(...)) was in the examples,
but didn't work (on() only works for memberCallExpr).
Fix a bug in the doc dump script that was introduced in r231575 when
removing a regexp capture without adapting the code that uses the
captures.

This change adds the new unroll metadata "llvm.loop.unroll.enable" which directs
the optimizer to unroll a loop fully if the trip count is known at compile time, and
unroll partially if the trip count is not known at compile time. This differs from
"llvm.loop.unroll.full" which explicitly does not unroll a loop if the trip count is not
known at compile time
With this change "#pragma unroll" generates "llvm.loop.unroll.enable" rather than
"llvm.loop.unroll.full" metadata. This changes the semantics of "#pragma unroll" slightly
to mean "unroll aggressively (fully or partially)" rather than "unroll fully or not at all".
The motivating example for this change was some internal code with a loop marked
with "#pragma unroll" which only sometimes had a compile-time trip count depending
on template magic. When the trip count was a compile-time constant, everything works
as expected and the loop is fully unrolled. However, when the trip count was not a
compile-time constant the "#pragma unroll" explicitly disabled unrolling of the loop(!).
Removing "#pragma unroll" caused the loop to be unrolled partially which was desirable
from a performance perspective.

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`.

This patch adds flags -fno-profile-instr-generate and
-fno-profile-instr-use, and the GCC aliases -fno-profile-generate and
-fno-profile-use.
These flags are used in situations where users need to disable profile
generation or use for specific files in a build, without affecting other
files.
