ed6ca58058 A32: Implement ASIMD VCEQ, VCGE, VCGT, VCLE, VCLT with zero
Fairly self-explanatory, we can leverage the existing IR functions for
the purpose of these instructions.

In the integer case, we can just insert function pointers
into an array and index it, given all comparison primitives exist
already for the integer side of things.

8808b8c479 cpu_info: Make test non-allocating
Same behavior, but makes it non-allocating by using a constexpr
std::array instead of a std::vector.

7f77a04900 fuzz_arm: Do not test vfp_VMRS
This may emit a vmrs *, fpscr instruction.
This results in fuzz failures due to slight inaccuracies in fpscr emulation.

* 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.
