9ca71b52aa aco: swap the correct v_mov_b32 if there are two of them 
Previously, this function tried to swap the instruction which is not
v_mov_b32, so that it doesn't introduce any new OPY-only instructions. If
both were v_mov_b32, it swapped Y. Since this makes Y opy-only, this can't
be done if X is also opy-only.

a780345e01 aco: fix compact_relocate_vars fallback with scc/exec/m0 precolored regs 
This probably doesn't fix anything in practice. I don't think this path is
ever taken for SGPRs except for pseudo-scalar transcendental instructions,
and those don't have any precolored operands/definitions.

f6581b41c4 aco/ra: don't require alignment for NPOT SGPR temporaries 
Aligning these can create situations where register allocation is
impossible. Only pseudo-instructions can use these, and they don't require
any alignment.

I'm not sure if these temporaries actually happen in practice. This
probably only affects the get_reg()'s compact_relocate_vars fallback path,
which doesn't usually happen for SGPRs.

623230a6ef aco/ra: change sorting in compact_relocate_vars 
D16 MIMG or pseudo-scalar transcendental instructions might give lower
limits to the maximum register available for their definitions, so just
try to place them earlier.

This is also part of fixing compact_relocate_vars with aligned NPOT
def/killed-op space (the second part is the later commit which changes
get_stride()).

ae6d4f1195 aco/ra: update_renames() before add_subdword_definition() 
The register file tests here should be done after update_renames().

Normally, get_reg() wouldn't have to move anything to make space for a 1-3
byte definition. This was encountered with skip_optimistic_path=true and a
get_reg_impl() bug (fixed in a later commit) which caused suboptimal
register assignment.
