[PATCH] Add pointer types to global named register

[Rafael Espíndola]

Please include a test with the new error.

I like Joeg and Reid suggestion of rejecting invalid sizes. For
example, a pointer should not go to eax on x86_64, but I think that
requires extra llvm support, no? If so, this patch LGTM, but please do
address their suggestion in a subsequent patch.

Thanks,
Rafael
