Returning false is always safe, because this means the exclusive write has failed.

94d0d33e02 Fix single stepping for certain instructions
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.

1ebc1895ee A32/x64: Create a global_offset optimization for the page table (#507)
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

25750ad2a2 A32/coprocessor: Remove lingering boost mention in documentation comment
This should have been changed to mention std::monostate, but was

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.

2e180a7f14 backend/x64/a32_interface: Mark Context move constructor and move assignment as noexcept
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.

0da5e949a8 Correct typo in DataCacheOperation enum
Fixes a typo for the InvalidateByVAToPoC enum entry. Given yuzu is the

away with changing this.
