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%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62193 91177308-0d34-0410-b5e6-96231b3b80d8
