This actually supports more of the extension than the LLVM backend but we
can't enable it because ACO doesn't work with all stages yet.
With more of it enabled, some CTS tests fail because our 64-bit sqrt
is very imprecise. I can't find any precision requirements for it
anywhere, so I'm thinking it might be a CTS issue.

This patch tries to give instructions with the same execution
mask also the same pass_flags and enables VN for SALU instructions
using exec as Operand.
This patch also adds back VN for VOPC instructions and removes VN for phis.
v2 (by Timur Kristóf):
- Fix some regressions.
v3 (by Daniel Schürmann):
- Fix additional issues

Previously, we used one hashset per BB, so that we could
always initialize the current hashset from the immediate
dominator. This patch changes the behavior to a single
hashmap using the block index per instruction to resolve
dominance.

ACO (short for AMD Compiler) is a new compiler backend with the goal to replace
LLVM for Radeon hardware for the RADV driver.
ACO currently supports only VS, PS and CS on VI and Vega.
There are some optimizations missing because of unmerged NIR changes
which may decrease performance.
