Hi doug.gregor,
This exposes SourceManager::isFromMainFile() through the libclang interface.
CODE_OWNERS doesn't seem to indicate an owner for libclang, so I'm pointing
this at Doug, but please let me know if there's someone more important.
I also couldn't find an obvious place to put a test for this. :(
