That makes the lld-link command line interface less compatible with MSVC
link, though. The goal of my change was to make 'lld-link -debug t.obj
-out:t.exe' make t.pdb, because I was trying to compare PDBs between lld
and MSVC.

I'd rather get the command line interface oriented towards making PDBs, fix
the invalid PDB issues, and move sanitizers over to PDBs than try to make
the lld-link command line interface support DWARF.
