The old logic would always emit LEA when both sources are in a register
and OE is disabled. However, ADD is still preferable when one of the
sources matches the destination.

- Refactor the Config::System::Main check so we check system once,
then we check for the section.
- Use an std::array<> instead of std::vector<>.
- Use an array of pointers instead of an array of ConfigLocation.
The latter contains two std::string objects, whereas pointers
are only 8 bytes (on 64-bit).

NOTE: The explicit std::string() conversions later are needed. Otherwise,
gcc-9.2.0 throws all sorts of errors because it can't find a matching
operator+() function.
"ppcState{}" is stored in the .data segment, which means the full ~4 MB
is stored in the executable.
"ppcState" is stored in the .bss segment, which means it only stores a
note that tells it to allocate and zero ~4 MB at runtime.
string_view is a thin wrapper around C strings, so it's more efficient
for constant strings than C++ strings.
The unordered_set<> also adds extra runtime overhead. For small arrays,
a simple linear search works. For larger arrays, std::binary_search()
works better than linear but without the unordered_set<> overhead.
ShouldBeDualLayer(): Removed a duplicate "SK8X52" entry.
This fixes Old AX Wii games having no audio when compiled under VS2019.
This also includes some minor code cleanup and moving a function to
avoid duplication.
The frame number is incremented before the first frame is swapped out.
Fixes ffmpeg creating invalid video files on output if the emulator only
runs for a single frame, e.g. FifoCI.
See the discussion in https://bugs.dolphin-emu.org/issues/11930.
(This probably doesn't really fix that issue, but it's something
I thought would make sense anyway.)
This was causing a race which was crashing the FifoCI runners. The main
thread called Stop() which in turn called ResetAllWiimotes() while the
emu thread was still exiting, also shutting down the Wiimote class.
By shifting the reset to the emu thread, all cleanup operations happen
on the same thread where they were initialized.
