  [AMDGPU] Refactor hazard recognizer for VALU-pipeline hazards. NFCI.

This is in preparation of handling these in scheduler. I do not expect
any changes to the produce code here, it is just an infrastructure.
Our current problem with the VALU pipeline hazards is that we only
insert V_NOP instructions in the hazard recognizer mode, but ignore
it during scheduling. This patch is meant to create a mechanism to
actually account for that during scheduling.
