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

int s1 = m1;
Teach SourceManager's content cache to keep track of whether its buffer was invalid when it was created, and use that bit to always set the "Invalid" flag according to whether the buffer is invalid. This ensures that all accesses to an invalid buffer are marked invalid, improving recovery. llvm-svn: 98690

// FIXME: This test fails inexplicably on Windows in a manner that makes it
// look like standard error isn't getting flushed properly.
XFAIL this test on that silly Windows platform. Grrr llvm-svn: 98750
