  AMDGPU/GlobalISel: Fix selecting llvm.amdgcn.s.getreg

This introduces the same bug llvm.amdgcn.s.setreg has where if the
user specified an immediate outside of the valid 16-bit range, it will
select into a verifier error.

  AMDGPU: Optimize copies to exec with other insts after exec def

It's possible to have terminator instructions after a write to exec,
so skip over them to find it.
