i965/vec4: Allow writemasking on math instructions on Gen7+.
The math instruction was Align1-only on Gen6 and we never updated this
to let it use Align16 features like writemasking on newer platforms.
total instructions in shared programs: 1686120 -> 1685507 (-0.04%)
instructions in affected programs: 48593 -> 47980 (-1.26%)
