They must both be applied "atomically" because the Clang changes depend on LLVM header changes (is there a way to avoid this problem without leaving in the old code in with a "don't touch, will be removed soon" comment?).
Please try to avoid revlock like that. You can just leave struct TableGenBackend around until it isn't used any longer.
Also, split the changes to lib/TableGen and include/llvm/TableGen into a third patch.

There's really no need for that. Backends don't go in libraries. Just stick everything in 'llvm'.

My general feeling is that it doesn't really matter, so best to just leave them. This is easily changed in a future patch if it is deemed desirable.
Leave them as is.
