Matt Arsenault f8bf7d7f42 AMDGPU: Don't fold copies to physregs ...

In a future patch, this will help cleanup m0 handling.

The register coalescer handles copies from a register that
materializes an immediate, but doesn't handle move immediates
itself. The virtual register uses will often be allocated to the same
register, so there end up being no real copy.
