i965: Align gen6 push constant size to dispatch width.
The FS backend is fine with register level granularity. But for the
brw_wm_emit.c backend, it expects pairs of regs to be used for the
constants, because the whole world is pairs of regs. If an odd number
got used, we went looking for interpolation in the wrong place.
