Fixes x86 instruction decoding.

Browse Source 
In the case of modrm + immediate then the immediate would end up
overwriting Src1 due to the the order of the decoding.
Changes Src1 and Src2 to an array and use a variable to index the array.
Causes a bit of code churn but fixes instruction decoding and allows
easier expansion in the future for instructions that have more sources
like AVX
