target/mips: Simplify Loongson MULTU.G opcode
Since MULTU opcodes don't record the most significant bits of the infinite result, sign-extending the sources make no difference in the result. Once we remove the sign extension of source registers, MULT and MULTU are identical (as are DMULT and DMULTU).
