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. llvm-svn: 354138
