[LLVMdev] debugloc metadata variation

Just working on some of the gmlt+fission debug info stuff and I came across
a comment that might be relevant to reducing the number of distinct
debugloc metadata nodes:

"or some sub-optimal metadata that
  // isn't structurally identical (see: file path/name info from clang,
  // includes the directory of the cpp file being built, even when the file
  // is absolute (such as an <> lookup header)))"

Seems that the file path/name isn't well canonicalized so as to allow
metadata level merging when linking. Might be helpful to figure out that
issue at some point.
