1449 (vsx_mov<mode>): Replace single move that handled all vector types
1450 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
1451 moves (when -mvsx-timode is in effect) into the main vector
1452 moves. Eliminate separate moves for <VSr> <VSa>, where the
1453 preferred register class (<VSr>) is listed first, and the
1454 secondary register class (<VSa>) is listed second with a '?' to
1455 discourage use. Prefer loading 0/-1 in any VSX register for ISA
1456 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
1457 that if the register was involved in a slow operation, the
1458 clear/set operation does not wait for the slow operation to
1459 finish. Adjust the length attributes for 32-bit mode. Use
1460 rs6000_output_move_128bit and drop the use of the string
1461 instructions for 32-bit movti when -mvsx-timode is in effect. Use
1462 spacing so that the alternatives and attributes don't generate
1463 long lines, and put things in columns, so that it is easier to
1464 match up the operands and attributes with the insn alternatives.
