b2f7a0e7ba A32: Implement ARM-mode SDIV/UDIV 
Now that we have Unicorn in place, we can freely implement instructions
introduced in newer versions of the ARM architecture.

c0ae23bbb7 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".

06ec6ab0da frontend/ir/cond: Remove unused invert() function 
This is no longer used by anything in the codebase, so it can be
removed.

4fc531f71b 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.

9309d95b17 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.

b5bf890584 load_store_*: Make bracing consistent and variables const where applicable 
Makes bracing consistent, and variables const where applicable to be
consistent with the rest of the codebase.

In most bracing cases, they'd need to be added to conditionals that
would involve checking stack pointer alignment in the future anyways.
