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
* Do not accidentally fuzz unimplemented unconditional instructions

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.

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.
