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.

13367a7efd A64: Match A32 page_table code 
Here we increase the similarity between the A64 and A32 front-ends in terms of their
page_table handling code. In this commit, we:

* Reserve and use r14 as a register to store the page_table pointer.
* Align the code to be more similar in structure.
* Add a conf member to A32EmitContext.
* Remove scratch argument from EmitVAddrLookup.

8b3bc92bce backend/x64: Reduce conversions required for cpsr_nzcv 
The guest program often accesses the NZCV flags directly much less

Therefore, we store our flags in cpsr_nzcv in a x64-friendly format.

This allows for a reduction in conditional jump related code.

92daae9513 A32/coprocessor: Remove boost from public interface 
Removes a boost header from the public includes in favor of using the
standard-provided std::variant.

The use of boost in public interfaces is often a dealbreaker for some
people. Given we use std::optional in the header already, we can
transition over to std::variant from boost::variant.

With this removal, this makes all of our dependencies internal to the
library itself.
