support mips release 6.
MIPS release 6 is not full compatible with the previous releases, it removes
some instructions and changes encoding of some instruction.
the `multu' is included.
MIPS r6 drops `lo' and `hi' registers, and then removes `multu'/`mfhi'/`mflo'.
Instead it uses `mulu' to compute the low part and `muhu' to compute
the high part.
