New Revision: 59179

URL: http://llvm.org/viewvc/llvm-project?rev=59179&view=rev
Log:
Add Preprocessor::PushIncludeMacroStack() and Preprocessor::PopIncludeMacroStack(), two utility methods for manipulating the Preprocessor stack.  These will be used to remove manually manipulation of IncludeMacroStack from the rest of the Preprocessor implementation.
