Chandler Carruth fcc965daa6 Prepare LLVM to fix PR14625, exposing a hook in MCContext to manage the
compilation directory.

This defaults to the current working directory, just as it always has,
but now an assembler can choose to override it with a custom directory.
I've taught llvm-mc about this option and added a test case.
