i965: Don't emit saturates for instructions without destinations.
We were special casing OPCODE_END but no other instructions that have no
destination, like OPCODE_KIL, leading us to emitting MOVs with null
destinations.
total instructions in shared programs: 5705243 -> 5701539 (-0.06%)
instructions in affected programs: 124104 -> 120400 (-2.98%)
