vc4: Stop trying to reuse temporaries that store uniform values.
Almost always, the MOV will get copy propagated out. Even if it doesn't, it's probably better to just reload the uniform at next use (to reduce register pressure) rather than try to save instruction count. I was looking at this because in the presence of texturing (which calls add_uniform() directly to get the uniform load forced into the instruction) the c->uniform_contents indices don't match 1:1 with the temporary qregs.
