v3d: writes to magic registers aren't RF writes after THREND

Shaders must not attempt to write to the register files in the last
three instructions, but that doesn't include the magic registers:

nop                  ; nop               ; thrsw; ldtmu.- *** ERROR ***
nop                  ; nop
nop                  ; nop

v2: Simplify validation rules. (Eric Anholt)
v3: Adjust validation even more. (Eric Anholt)
