[PATCH] D35224: [lld/pdb] Create an empty public symbol records stream

[Zachary Turner via Phabricator via llvm-commits]

zturner created this revision.

This creates a public symbol hash stream and public symbol records stream, each completely empty.  This allows us to get more fields matching up in the pdb diff test, so that test is updated.

Eventually we will need to come up with a clever algorithm for diffing symbol //records//, but for now at least this gets us one step closer.

link still doesn't like our PDBs even after this change, so the next thing to check would be creating an empty globals stream.
