Not entirely sure how we didn't hit this before, but dropping the const
initializer on the floor is obviously not correct.

No idea why i965 even still uses this pass, vs nir scalarizing pass.
So might want to drop this. But I figured fixing it first gives
something that can be cherry-picked to release branches, so this
patch should land before deleting the ir pass.
