Matt Arsenault 39337ff2dc AMDGPU: Handle cvt_scale F32/F16->F4/F8 gfx950 hazard (#117844) ...

gfx950 SP changes doc says:
No 4 clk forwarding on opcodes that convert from
F32/F16->F8 or F32/F16->F4. Must insert a NOP or
instruction writing some other destination VREG
after a conversion to F4/F8 since it writes either
low/high half or bytes.
