11828 moves. Eliminate separate moves for <VSr> <VSa>, where the
11829 preferred register class (<VSr>) is listed first, and the
11830 secondary register class (<VSa>) is listed second with a '?' to
11831 discourage use. Prefer loading 0/-1 in any VSX register for ISA
11832 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
11833 that if the register was involved in a slow operation, the
11834 clear/set operation does not wait for the slow operation to
11835 finish. Adjust the length attributes for 32-bit mode. Use
11836 rs6000_output_move_128bit and drop the use of the string
11837 instructions for 32-bit movti when -mvsx-timode is in effect. Use
11838 spacing so that the alternatives and attributes don't generate
11839 long lines, and put things in columns, so that it is easier to
11840 match up the operands and attributes with the insn alternatives.
