N3DS-only option. See config.ini for details and context. This should
make very demanding games (those which already use 3x clockrate and L2C
by default, like Pokémon US/UM) between 5 to 15% faster. Not widely

Virtually full support for 5.x except that svcUnmapProcessMemoryEx will be forwarded to svcUnmapProcessMemory (both are equivalent for up to 64MB chunks)
