Previously, lld-link would use a random byte sequence as the PDB GUID. Instead, use a hash of the PDB file contents. To not disturb llvm-pdbutil pdb2yaml, the hash generation is an opt-in feature on InfoStreamBuilder and ldb/COFF/PDB.cpp always sets it. Since writing the PDB computes this ID which also goes in the exe, the PDB writing code now must be called before writeBuildId(). writeBuildId() for that reason is no longer included in the "Code Layout" timer. Since the PDB GUID is now a function of the PDB contents, the PDB Age is always set to 1. There was a long comment above loadExistingBuildId (now gone) about how not changing the GUID and only incrementing the age was important, but according to the discussion in PR35914 that comment was incorrect.
