i965/vec4: Relax writemask condition in CSE
If the previously seen instruction generates more fields than the new
instruction, still allow CSE to happen. This doesn't do much, but it
also enables a couple more shaders in the next patch. It helped quite a
bit in another change series that I have (at least for now) abandoned.
v2: Add some extra comentary about the parameters to instructions_match.
Suggested by Ken.
No changes on Skylake, Broadwell, Iron Lake or GM45.
