cmd/compile: indexed loads/stores can't be faultOnNilArg0

Because of the index, these ops can't guarantee faulting if arg0 is nil.

Clean up the PPC64 index ops - they can't take a sym or an offset.

Noticed while debugging #37881. I don't think it is the cause, but I guess
there is a chance.
Update #37881
