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. git-svn-id: 91177308-0d34-0410-b5e6-96231b3b80d8
