63b18e9e5b aco: move return address to a clobbered register
It's placed in the preserved registers, but the p_call clobbers it, so
this change removes some special casing.

a2b70ce4ec aco/isel: remove uniform reduce/scan optimization
This is now done in NIR, with the exception of exclusive min/max/and/or scans.
But those are not really useful, and if we ever come across them we can
optimize them in NIR using write_invocation_amd.

No Foz-DB changes on Navi21.

ca25553b92 aco: add a post-RA pass to disable wqm
By disabling WQM post-RA, we don't have RA/spilling mov issues with image_sample
operands that need to be computed in WQM.

We also don't restrict scheduling by inserting exec writes.
The only downside is more scalar ALU usage, but the SALU is almost always underutilized.
