[PATCH] D33323: [llvm-pdbdump] Add the ability to merge PDBs

[Zachary Turner via Phabricator via llvm-commits]

zturner created this revision.

By adding a new `merge` subcommand, we can now give arbitrarily many PDBs to `llvm-pdbdump` as inputs and get back one PDB.  Currently it only merges type streams and ignores everything else.  In the future it can merge symbol streams, module information, and other types of stuff.

Having this command allows us to write a test for type merging, which is also done in this patch.
