12676 (vsx_mov<mode>): Replace single move that handled all vector types
12677 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
12678 moves (when -mvsx-timode is in effect) into the main vector
12679 moves. Eliminate separate moves for <VSr> <VSa>, where the
12680 preferred register class (<VSr>) is listed first, and the
12681 secondary register class (<VSa>) is listed second with a '?' to
12682 discourage use. Prefer loading 0/-1 in any VSX register for ISA
12683 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
12684 that if the register was involved in a slow operation, the
12685 clear/set operation does not wait for the slow operation to
12686 finish. Adjust the length attributes for 32-bit mode. Use
12687 rs6000_output_move_128bit and drop the use of the string
12688 instructions for 32-bit movti when -mvsx-timode is in effect. Use
12689 spacing so that the alternatives and attributes don't generate
12690 long lines, and put things in columns, so that it is easier to
12691 match up the operands and attributes with the insn alternatives.
