AMDGPU: Stop implementing shouldCoalesce (#168988) 
Use the default, which freely coalesces anything it can.
This mostly shows improvements, with a handful of regressions.
The main concern would be if introducing wider registers is more
likely to push the register usage up to the next occupancy tier.
