arch/mips/isa/decoder.isa:
Fix mult and multu instructions. This semantic error causes the problem: <int64> = <int32> * <int32>. Although I was placing
the output into a 64-bit integer the multiply was just doing a 32-bit multiply so the solution is to just use
the 'sd' & 'ud' operands so that the ISA parser will use the int64_t and uint64_t types in calculation.
