16094 that if the register was involved in a slow operation, the
16095 clear/set operation does not wait for the slow operation to
16096 finish. Adjust the length attributes for 32-bit mode. Use
16097 rs6000_output_move_128bit and drop the use of the string
16098 instructions for 32-bit movti when -mvsx-timode is in effect. Use
16099 spacing so that the alternatives and attributes don't generate
