[PATCH] D51887: lld-link: Set PDB GUID to hash of PDB contents instead of to a random byte sequence.

I wonder if you can just compute a hash for a mmap'ed PDB file instead of defining a new type of Stream. That's what we do for ELF when computing a build-id, and I found that's easy to do. It is also easy to parallelize hash computation by making it a tree hash.
