aco: value number instructions using the execution mask

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
