b50114ae70 A64/fuzz_with_unicorn: Avoid repeated unnecessary library calls in RunTestInstance() 
Repeatedly retrieving the vectors and registers from unicorn involves
copying the entire set of registers and vectors by value instead of
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.

97277c598b A32: Rename vfp2-related files to vfp 
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.

c098ade2e7 dynarmic_tests: Resolve CPSR discrepancies in tests 
Unicorn internally checks if the LSB is set in order to determine
whether or not it should assume thumb mode internally. Clearing this

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.

d29582a0e1 A32: Fuzz instructions using unicorn 
While skyeye was OK previously, now that we have an AArch64 backend,
this also means that we eventually have to support the AArch32
counterpart to it. Unfortunately, SkyEye is only compatible up to
ARMv6K, so we woud need to do a lot of work to bring the interpreter up
to speed with things to even begin testing new instruction
implementations.

For the AArch64 side of things, we already use Unicorn, so we can toss
out SkyEye in favor of it instead.

134bb02e19 ir/value: Replace includes with forward declarations 
enum classes are still considered complete types when forward declared
(as the compiler knows the exact size of the type from the declaration
alone). The only difference in this case being that the members of the
enum class aren't visible. Given we don't use the members within this
header in any way, we can simply forward declare them here and remove
the inclusions.

4acc481463 translate_arm/load_store: Handle unpredictable instructions 
This necessated handling literal versions of the instructions separately
as they had different requirements. The rationale for detecting
unpredictable instructions is because:

a. they are unlikely to be outputted by a well-behaved compiler
b. their behaviour may change between different processors

I would rather unpredictable instructions fail loudly than silently do
approximately the right thing.
