I've mostly deferred this problem to a later date but I have made slight tweaks
to make the zero-extension explicit by renaming GIR_CopyConstantAsImm to
GIR_CopyConstantAsUImm. It's up to tablegen to decide whether to sign-extend or
zero-extend the constant but right now it can only choose zero-extend.
