Reid Kleckner c50349d4c6 [PDB] Finish and simplify TPI hashing
Summary:
This removes the CVTypeVisitor updater and verifier classes. They were
made dead by the minimal type dumping refactoring. Replace them with a
single function that takes a type record and produces a hash. Call this
from the minimal type dumper and compare the hash.

I also noticed that the microsoft-pdb reference repository uses a basic
CRC32 for records that aren't special. We already have an implementation
of that CRC ready to use, because it's used in COFF for ICF.

I'll make LLD call this hashing utility in a follow-up change. We might
also consider using this same hash in type stream merging, so that we
don't have to hash our records twice.

Zachary Turner f8a2e04812 [llvm-pdbutil] Add back the ability to dump hashes and index offsets.
This was regressed in a previous patch that re-wrote the dumper,
and I'm incrementally adding back the pieces that are missing.
