Hi, Luke

My suggestion is that the GCC support for SV look at print_operand()
case '0' to adjust the register names and rs6000_asm_output_opcode()
to adjust the mnemonic instead of changing the output template of all
patterns.  One can mark patterns as allowing SV, similar to prefixed
instructions attributes.

I'm requesting that any changes be as localized and inconspicuous as
possible.  Adding attributes and updating the patterns that emit
instructions keeps the changes less visible in the impact on the rest
of the port.

Thanks, David
