1638         (vsx_mov<mode>): Replace single move that handled all vector types
1639         with separate 32-bit and 64-bit moves.  Combine the movti_<bit>
1640         moves (when -mvsx-timode is in effect) into the main vector
1641         moves.  Eliminate separate moves for <VSr> <VSa>, where the
1642         preferred register class (<VSr>) is listed first, and the
1643         secondary register class (<VSa>) is listed second with a '?' to
1644         discourage use.  Prefer loading 0/-1 in any VSX register for ISA
1645         3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
1646         that if the register was involved in a slow operation, the
1647         clear/set operation does not wait for the slow operation to
1648         finish.  Adjust the length attributes for 32-bit mode.  Use
1649         rs6000_output_move_128bit and drop the use of the string
1650         instructions for 32-bit movti when -mvsx-timode is in effect.  Use
1651         spacing so that the alternatives and attributes don't generate
1652         long lines, and put things in columns, so that it is easier to
1653         match up the operands and attributes with the insn alternatives.
