Allow x86 to build with assembly for enable all - disable assembly when x86 and not assembly code available. Add file fe_operations.c when assembly and x86.
x86: fix ECB decrypt to use corect offsets for parameters
fix AES-NI and AVX1 assembly code
fix sp_int with assembly to compile
minor optimizations of AES-GCM
x64: Don't emit move instruction if source and destination are the same reg
Use xor instead of mov 0
