emit_uniformize() emits SHADER_OPCODE_FIND_LIVE_CHANNEL with its flag_subreg set, so that the IR knows which flag is accessed. However the flag is only used on Gen7 in Align1 mode. To avoid setting unnecessary bits in the instruction words, get the information we need and reset the default flag

emit_uniformize() emits SHADER_OPCODE_FIND_LIVE_CHANNEL with its flag_subreg set, so that the IR knows which flag is accessed. However the flag is only used on Gen7 in Align1 mode, and it is used as an explicit source and destination. To avoid setting unnecessary bits in the instruction words,
