Summary: This is a first step towards getting line info to show up in VS and windbg. So far, only llvm-pdbutil can parse the PDBs that we produce. cvdump doesn't like something about our file checksum tables. I'll have to dig into that next. This patch adds a new DebugSubsectionRecordBuilder which takes bytes directly from some other producer, such as a linker, and sticks it into the PDB. Line tables only need to be relocated. No data needs to be rewritten. File checksums and string tables, on the other hand, need to be re-done.
