intel/compiler: Set swizzle to BRW_SWIZZLE_XXXX for scalar region
When RepCtrl is set, the swizzle field is ignored by the hardware. In
order to ensure a 1-to-1 correspondence between the human-readable
disassembly and the binary instruction encoding always set the swizzle
to XXXX (all zeros) when it is unused due to RepCtrl
