Several issues:
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.
Instead of looking up the page table like:
table[addr >> 12][addr & 0xFFF]
We can use a global offset on the table to query the memory like:
table[addr >> 12][addr]
This saves two instructions on *every* memory access within the recompiler.
Original change by degasus in A64 emitter

Thanks at skmp for the idea.
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.
Provides a more "correct" move constructor/assignment operator, since
these relevant functions shouldn't throw exceptions.
Has the benefit of playing nicely with std::move_if_noexcept and other
noexcept library facilities.
Fixes a typo for the InvalidateByVAToPoC enum entry. Given yuzu is the
only known user of 64-bit mode and it doesn't use this value, we can get
away with changing this.
The purpose of this instruction is to raise exceptions when certain decode-time
issues happen, instead of asserting at translate time. This allows us to
use the translator for code analysis without worrying about unnecessary asserts,
but also provides flexibility for the library user to perform custom behaviour
when one of these states are raised.
