[PATCH] [prototype] Adding line table debug information to LLVM on Windows

I've looked how file/dir handling is done in Clang and I think these strings are always stored/obtained separately.
I don't think there's a single place in the Clang codebase where they are merged together into a full filepath string.
I decided to write a dozen of lines in WinCodeViewLineTables.cpp to handle canonicalization of Windows filepaths rather than threading extra info from Clang to IR to LLVM in a cross-platform way...
After all, we only have one "user" of this data as of now.
Do you think this's reasonable?
