[PATCH] D34257: [PDB] Start emitting source file and line information

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.

There's a lot of room for improvement in this code. The linker really
doesn't need to be doing this much deserialization. All it needs to do
is to copy the line tables and relocate them in the PDB. Currently we
copy the line tables, relocate them, deserialize them, and then use
high-level APIs to insert them into the PDB. All of that work is
basically unnecessary, but it's a start.
