A couple fixes for preprocessor expressions:
...
1. Be more tolerant of comments in -CC (comment-preserving) mode. We were missing a few cases.
2. Make sure to expand the second FOO in "#if defined FOO FOO". (See also
r97253, which addressed the case of "#if defined(FOO FOO".)
Fixes PR10286.

Fix diagnostic pragmas.
...
Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.
Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.
Fixes rdar://8365684.
