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.

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.

b50114ae70 A64/fuzz_with_unicorn: Avoid repeated unnecessary library calls in RunTestInstance() 
Repeatedly retrieving the vectors and registers from unicorn involves

simply retrieving a reference to them. Instead, we can just do the work
once and print out the values.

While we're at it, also make our bracing consistent.

c098ade2e7 dynarmic_tests: Resolve CPSR discrepancies in tests

0b15fc9755 a32/fuzz_arm: Use same fuzzing mechanism as AArch64 
Introduces the same fuzzing mechanism used by the AArch64 code for
fuzzing instruction implementations, getting rid of the need to
manually specify the instruction generator sequences--replacing it with
an instruction blacklist instead.

Much of this change originates from a previous patch made by Mary. This
just makes it interact nicely with the alterations made to get Unicorn
to cooperate properly.

4f2b60c8e7 dynarmic_tests: Remove skyeye interpreter 
This is quite a messy interpreter and would require a large amount of
work to bring it up to speed to begin implementing newer portions of the
AArch32 instruction set into Dynarmic.

Given we already have fuzzing with Unicorn set up for
AArch64/AArch32, we can get rid of this and unify our testing
infrastructure.

This will also make building the tests much faster, given a whole
interpreter doesn't need to be built anymore as part of the project.
