  [AMDGPU] Speedup canBeVOPD()

Generate static table from tablegen instead of trying to
create a full VOPD opcode just to see if that is possible.

Ideally it shall be single table with info for both X and
Y components and non-VOPD opcode as a primary key, although
I do not think we can genere it now.
