PTH:
- Use canonical FileID when using getSpelling() caching. This
addresses some cache misses we were seeing with -fsyntax-only on
Cocoa.h
- Added Preprocessor::getPhysicalCharacterAt() utility method for
clients to grab the first character at a specified sourcelocation.
This uses the PTH spelling cache.
- Modified Sema::ActOnNumericConstant() to use
Preprocessor::getPhysicalCharacterAt() instead of
SourceManager::getCharacterData() (to get PTH hits).
These changes cause -fsyntax-only to not page in any sources from
Cocoa.h. We see a speedup of 27%.
