The finding was that 99% of the time, textures are static in memory. However, Dolphin would pessimistically continue to decode and copy the same texture every time. The optimisation is to check if the texture matches what is in the cache, and if it does, Dolphin should early exit.
The result is the speed in New Super Mario Bros Wii increased 35% with spinning coins. Still not as fast as EFB copy to texture though.

Upon texture reloading, the cache entry hash wasn't updated and thus we effectively disabled any texture caching in that case.

Now, there are two:
Real dimensions: Width and height of the original GameCube texture
Virtual dimensions: Width and height of the texture used by dolphin-emu's renderer

Work around different gcc versions giving conflicting warnings
about signed/unsigned comparisons involving bit fields.
