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.

Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).
There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable.
