Introduce optional "Invalid" parameters to routines that invoke the SourceManager's getBuffer() and, therefore, could fail, along with Preprocessor::getSpelling(). Use the Invalid parameters in the literal parsers (string, floating point, integral, character) to make them robust against errors that stem from, e.g., PCH files that are not consistent with the underlying file system. I still need to audit every use caller to all of these routines, to determine which ones need specific handling of error conditions. llvm-svn: 98608

Audit all Preprocessor::getSpelling() callers, improving failure recovery for those that need it. llvm-svn: 98689
