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.

This may emit a vmrs *, fpscr instruction.
This results in fuzz failures due to slight inaccuracies in fpscr emulation.

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.
