[AMDGPU] Should v_permlane64_b32 be handled in fixVcmpxPermlaneHazards?

[DadSchoorse]

The GFX11 ISA doc says:

7.2.8. PERMLANE Specific Rules
V_PERMLANE may not occur immediately after a V_CMPX. To prevent this, any other VALU opcode may be
inserted (e.g. V_NOP).

As there is no restriction to v_permlane(x)16, should isPermlane be updated to include v_permlaneb64_b32?

I'd assume yes
