i965/vs: Protect pow(x,y) MOV of y on gen4 from other instruction flags.

I don't know if it was possible to trigger this bug -- we don't merge
saturates into the math instruction because we're bad at coalescing currently,
and there's nothing generating these with predicates.  Still, let's avoid
future bugs when we do smarter codegen.
