Matt Arsenault 124384f08d AMDGPU: Fix immediate folding logic when shrinking instructions
If the literal is being folded into src0, it doesn't matter
if it's an SGPR because it's being replaced with the literal.

Also fixes initially selecting 32-bit versions of some instructions
which also confused commuting.

Matt Arsenault c8e2ce4046 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.
