This avoids out-of-bounds warnings when replaying FIFO captures.
The value of XF_REGS_SIZE is written into the DFF header and we only
read the min of XF_REGS_SIZE and the header value, so this change is
backward compatible and doesn't break forward compatibility for old
Dolphin versions either.
This 'absolutely not' a read of uninitialized memory is '100% not'
the cause of our non-deterministic behavior on the Intel NUC.
If there was a such an error, it would show up on all FifoCi
backends equally. This is 'probably' unrelated to the fact that
the Intel NUC is the only fifoci runner not running under virtualization.
Texture updates have been moved into TextureCache, while
TMEM updates where moved into bpmem. Code for handling
efb2ram updates was added to TextureCache.
There was a bug for preloaded RGBA8 textures, it only copied
half the texture. The TODO was wrong too.
