1b25e867ae asimd_load_store_structures: Simplify ToExtRegD()
ExtReg has a supplied operator+, so we can make use of that instead.

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
* Do not accidentally fuzz unimplemented unconditional instructions

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.

349d4b577a General: Remove unnecessary includes
Removes unnecessary header dependencies that have accumulated over time
as changes have been made. Lessens the amount of files that need to be
rebuilt when the headers change.

9365487797 frontend/A32/ir_emitter: Remove unnecessary includes
std::initializer_list isn't used anywhere in here, and we can just
forward declare the CoprocReg enum to avoid needing to include the
header.

Now that we fuzz against Unicorn, we aren't just restricted to VFPv2.
VFPv3 and VFPv4 facilities can now be implemented. This renames
constructs mentioning VFPv2 to just refer to VFP.
