668259ef0b aco/scheduler: move clauses through RAR dependencies
Some checks are pending

Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
For simplicity, we limit this feature to only one RAR-dependency per clause.
This allows to quickly correct the register demand changes that occur by
switching the kill flags.

f0c613765c aco: Add preload_preserved pseudo instruction 
These are helper instructions for the spill_preserved pass to insert
reloads for registers that are preserved by the ABI, yet
clobbered by the callee shader.

There is one p_reload_preserved instruction at the end of each block.
This allows us to insert reloads early, to alleviate the high latency of
scratch reloads.

d3743dd7ba aco/scheduler: improve scheduling heuristic
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
The heuristic we are currently using still stems from the GCN era
with the only adjustments being made for RDNA was to double (or triple)
the wave count.

This rewrite aims to detangle some concepts and provide more consistent results.

 - wave_factor: The purpose of this value is to reflect that RDNA SIMDs can
                accomodate twice as many waves as GCN SIMDs.
 - reg_file_multiple: This value accounts for the larger register file of wave32
                      and some RDNA3 families.
 - wave_minimum: Below this value, we don't sacrifice any waves. It corresponds
                 to a register demand of 64 VGPRs in wave64.
 - occupancy_factor: Depending on target_waves and wave_factor, this controls
                     the scheduling window sizes and number of moves.

The main differences from the previous heuristic is a lower wave minimum and
a slightly less aggressive reduction of waves.
It also increases SMEM_MAX_MOVES in order to mitigate some of the changes
from targeting less waves.
