Matt Arsenault 90c7593a75 AMDGPU: Remove global isGCN predicates
These are problematic because they apply to everything,
and can easily clobber whatever more specific predicate
you are trying to add to a function.

Currently instructions use SubtargetPredicate/PredicateControl
to apply this to patterns applied to an instruction definition,
but not to free standing Pats. Add a wrapper around Pat
so the special PredicateControls requirements can be appended
to the final predicate list like how Mips does it.

Matt Arsenault e135c4c6a6 AMDGPU: Add tied operands to v_mad_mix{lo|hi}_f16
These write to the low and high half of the destination
register and leave the other 16-bits unchanged. This is true
for most 16-bit instructions on gfx9, but we don't use that
now.

Matt Arsenault 76935122cc AMDGPU: Start selecting v_mad_mixlo_f16
Also add some tests that should be able to use v_mad_mixhi_f16,
but do not yet. This is trickier because we don't really model
the partial update of the register done by 16-bit instructions.

Matt Arsenault c8f8cda0cd AMDGPU: Correct operand types for v_mad_mix*
These aren't really packed instructions, so the default
op_sel_hi should be 0 since this indicates a conversion.
The operand types are scalar values that behave similar
to an f16 scalar that may be converted to f32.

Doesn't change the default printing for op_sel_hi, just
the parsing.
