dyncom: Move over QADD16/QASX/QSAX/QSUB16

More warning cleanups

CMake: Turn MSVC optimizations up to 11

dyncom: Move SEL over

CFG: Implemented the GetConfigInfoBlk2 function.

dyncom: Move over SASX/SSAX/SADD16/SSUB16

Hopefully this will make people stop thinking it's a hard dependency.

While not having a noticeable effect on CPU-bound applications, this
change gives an about 30-50% increase in performance for games using
the GPU.

Moved most of the shared CFG code there, implemented a few CFG:I functions

That's the language id block, we're using LANGUAGE_EN for now. This block allows some games to boot further

It is now kept in memory as per 3dbrew, all updates happen on memory, then they can be saved using UpdateConfigNANDSavegame.

Seems to allow some games to boot further, thanks @Normmatt for sharing this information

Added a "config" file to the CFG process service (CFG:U), and added a few default blocks to it.

Implemented GetSystemModel and GetModelNintendo2DS

License change

Added CreateFile to the FS_USER service

Tested with hwtests.

armemu: Implement SADD8/SSUB8
