Uncovered a bug within Thread's SetCoreAndAffinityMask() where an
unsigned variable (ideal_core) was being compared against "< 0", which
would always be a false condition.
We can also get rid of an unused function (GetNextProcessorId) which contained a sign
mismatch warning.
Quite frequently there have been cases where code has been merged into
the core that produces warning. In order to prevent this from occurring,
we can make the compiler flag these cases and allow our CI to flag down
any code that would generate these warnings.
This is beneficial given silent conversions from signed/unsigned can
result in logic bugs. This forces one writing changes to be explicit
about when signedness conversions are desirable, rather than leaving it
up to readers' interpretation.
Currently the codebase isn't in a state where it will build successfully
with this change applied, but this will be addressed in subsequent
follow-up changes. This set of changes will focus on making it build
properly with these changes for MSVC as a starting point for basic
coverage.
- This does not actually seem to exist in the real kernel - games reset these automatically.

After further hardware investigation, it appears that some games, perhaps those more lazily coded, will not call EnsureSaveData, meaning that they expect the normal (current) save to be automatically made. Additionally, some games do not create a cache or temporary save before use.
In these 3 specific instances, the save is created automatically for the game if it doesn't exist.
While not an issue, it does prevent fallthrough from occurring if
anything is ever added after this case (unlikely to occur, but this
turns a trivial "should not cause issues" into a definite "won't cause
issues).
While a map is an OK way to do lookups (and usually recommended in most
cases), this is a map that lives for the entire duration of the program
and only deallocates its contents when the program terminates.
Given the total size of the map is quite small, we can simply use a
std::array of pairs and utilize std::find_if to perform the same
behavior without loss of performance.
This eliminates a static constructor and places the data into the
read-only segment.
While we're at it, we can also handle malformed inputs instead of
directly dereferencing the resulting iterator.
In case of redundant yields, the scheduler will now idle the core for
it's timeslice, in order to avoid continuously yielding the same thing
over and over.
