15990 secondary register class (<VSa>) is listed second with a '?' to
15991 discourage use. Prefer loading 0/-1 in any VSX register for ISA
15992 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
15993 that if the register was involved in a slow operation, the
15994 clear/set operation does not wait for the slow operation to
15995 finish. Adjust the length attributes for 32-bit mode. Use
15996 rs6000_output_move_128bit and drop the use of the string
15997 instructions for 32-bit movti when -mvsx-timode is in effect. Use
15998 spacing so that the alternatives and attributes don't generate
15999 long lines, and put things in columns, so that it is easier to
16000 match up the operands and attributes with the insn alternatives.
