backend/x64: Reduce conversions required for cpsr_nzcv
...
The guest program often accesses the NZCV flags directly much less
often than we need to use them for jumps and other such uses.
Therefore, we store our flags in cpsr_nzcv in a x64-friendly format.
This allows for a reduction in conditional jump related code.
