fix mips r6 syscall clobber lists not to include hi/lo registers

mips r6 (an incompatible isa from traditional mips) removes the hi and
lo registers used for mul/div results. older gcc versions accepted
them in the clobber list for asm, but their presence is incorrect and
breaks on later versions.

in the process of fixing this, the clobber list for 32-bit mips
syscalls has been deduplicated via a macro like on mips64 and n32.
