eb332b3836 asimd_three_same: Unify BitwiseInstructionWithDst with BitwiseInstruction
Now that all bitwise instructions are implemented, we can unify all of
them together using if constexpr.

6df660c889 fuzz_arm: Ensure all instructions are fuzzed
* VFP instructions were not getting fuzzed due to matching coprocessor instructions (as invalid instructions)
* Fix VPOP writeback for doubles when (imm8 & 1) == 1

8b3bc92bce 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.

94d0d33e02 Fix single stepping for certain instructions
Several issues:
1. Several terminal instructions did not stop at the end of a single-step block
2. x64 backend for the A32 frontend sometimes polluted upper_location_descriptor with the single-stepping flag

We also introduce the enable_optimizations parameter to the A32 frontend.
