Calculate the split penalty upfront.

This is
a) More efficient.
b) Important as we move forward with further metrics for penalty.

No functional changes intended.

Split ">>" in "A<B<C> >" in Chromium style.

It needs to be compatible with C++03.

Allow all parameters on next line for function calls in Chrome.

The style guide only forbids this for function declarations. So,
now

someFunction(
    aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa, aaaaaaaaaaaa);

Is allowed in Chromium mode.

Mark a struct definition in an objc container with the TopLevelDeclInObjCContainer bit.

Fixes accurately getting a cursor inside an objc container containing a struct definition,
from a PCH/preamble file.

Improve formatting of code with comments.

Before:
aaaaaaa(aaaaaa( // comment
                aaaaaaa));
<big mess>

After:
aaaaaaa(aaaaaa( // comment
    aaaaaaaa));
function(/* parameter 1 */ aaaaaaa,
         /* parameter 2 */ aaaaaaa,
         /* parameter 3 */ aaaaaaa,
         /* parameter 4 */ aaaaaaa);

(the latter example was only wrong in the one-arg-per-line mode, e.g. in
Google style).

[driver] Refactor the driver so that a failing commands doesn't prevent
subsequent commands from being executed.

The diagnostics generation isn't designed for this use case, so add a note to
fix this in the very near future.  For now, just generated the diagnostics for
the first failing command.

[Preprocessor] When checking if we can concatenate two tokens, check
if they were already concatenated in source using the spelling locations
even if they came from a macro expansion.

This fixes an issue where a GUID passed as macro argument ends up
malformed after preprocessing because we added spaces inside it.

Move the token annotator into separate files.

Don't fixit/recover from -Wstatic-float-init when it's not an error.

[ubsan] Implement the -fcatch-undefined-behavior flag using a trapping
implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.

The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred.  Eventually, the -fcatch-undefined-behavior' flag will be removed.

[Frontend] Make the include dir group independent from the "use sysroot" bit.

 - This slightly decouples the path handling, since before the group sometimes
   dominated the "use sysroot" bit, but it was still passed in via the API.

 - No functionality change.
