Matt Arsenault bb9c0afde5 AMDGPU: Reduce number of copies emitted
Instead of always inserting a copy in case
the super register is itself a subregister,
only extract to the super reg class if this is
actually the case.

This shouldn't really change codegen, but
makes looking at the output of SIFixSGPRCopies
easier to read.
