This is similar to what RADV implements using the NIR_LOOP_PASS
helpers. I have not used those helpers for a couple of reasons:
1. They use the pointer to the optimization function, which doesn't
work if the same function is called multiple times in one invocation
of the loop (fixable)
2. After fixing them, due to Intel's use of sub-expressions, the amount
of code added to wrap the shared macro becomes more than simply
reimplementing them for the Intel compiler
On most workloads the results are a wash, but on compile heavy
workloads like Cyberpunk 2077 and Rise of the Tomb Raider, I saw
fossil-db runtimes fall by 1-2% on my ICL, with no changes to the
compiled shaders. Caio saw closer to 2.5% on TGL.
