freedreno/ir3: use nopN encoding when possible

Use the (nopN) encoding for slightly denser shaders.. this lets us fold
nop instructions into the previous alu instruction in certain cases.

Shouldn't change the # of cycles a shader takes to execute, but reduces
the size.  (ex: glmark2 refract goes from 168 to 116 instructions)

Currently only enabled for a6xx, but I think we could enable this for
a5xx and possibly a4xx.
