From 44d798d9763bc32aaf49fe7c10d604845f4b6685 Mon Sep 17 00:00:00 2001

Subject: Add support for a new extension to the .file directive:

  .file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.
