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.

A32/translate_thumb: Clean up formatting 
Performs a similar tidying up of the Thumb translator, like what was
done with the regular ARM translator to make it consistent with the rest
of the codebase.

The A32 backend (both Thumb and ARM), will likely see more changes to it
in the near future, so this just acts as a "dusting off".

frontend/ir/cond: Remove unused invert() function 
This is no longer used by anything in the codebase, so it can be
removed.

ir/basic_block: Forward declare headers where applicable 
Now that the constructor and destructors have been placed within the cpp
file, we can forward declare the memory pool data structures. Now, a
change to the memory pool code won't ripple across the entirety of the
IR emitter.

ir/block: Default ctor and dtor in the cpp file 
Prevents potentially inlining allocation code everywhere. While we're at
it, also explicitly delete/default the copy/move constructor/assignment
operators to be explicit about them.

common/fp/info: Make half-precision info struct functions return correctly sized types 
While initially done to potentially prevent creating bugs due to C++
having a silly type-promotion mechanism involving types < sizeof(int)
and unsignedness, given that the bulk of these functions' usages
are on exit paths, these can return the correct type to avoid the need
to cast at every usage point.
