The Verifier is separate from the MachineVerifier, so move it to a
different directory. Some other verifier tests were scattered in
target codegen tests as well (although I'm sure I missed some). Work
towards using a more consistent naming scheme to make it clearer where
the gaps still are for generic instructions.
