Fix C aggregate-passing ABI on powerpc

The existing code (which looks like it was copied from MIPS) passes
aggregates by value in registers. This is wrong. According to the SVR4
powerpc psABI, all aggregates are passed indirectly.

See #64259 for more discussion, which addresses the ABI for the special
case of ZSTs (empty structs).
