d3d: Avoid rewriting textures, just swizzle.
...
Luckily A is in the same place and the same width, so we can do this for
all but framebuffers easily.
Technically we could do it in OpenGL as well.
Small (1-2%) performance improvement in FF2.

Optimize double alpha blending for 1/0 textures.

If the blend is 2*a / 1-a, and the alpha is either 1 or 0, we can still
use color doubling instead. Fixes #3379 (Persona 2.)

Use flags to avoid hashing textures when unchanged.
...
If only parameters change (like wrapping or clut, etc.) we don't need to
rehash the data - we know it hasn't changed.
Should reduce the distance between lazy texture hashing on and off.

Add a conservative check that prevents alpha testing in a few cases.
...
This will become really powerful if we add some code to the vertex decoder
to check for non-full alpha in the vertices, and set gstate_c.vertexFullAlpha if none
is found (probably want to do the reverse, set it to true and clear if any non-255 alpha is found).
Alpha testing is a performance killer on many mobile GPUs so big efforts to
avoid it can be worth it.

It's actually already pretty decent (unlike the softgpu), but there were a
few places it could use a bit of help. Speeds up things with hardware
transform off, or areas that need to use software transform.

softgpu: Don't mask out so much of fb stride.

Seems like anything from 4 is supported in 8888, most likely it just needs
to align to 16 bytes. Values above 1024 work, but e.g. 2044 seems buggy.

The bezier/spline code will no longer need to handle morph and splines,

Speedup a few 2D games on mobile by eliminating the alpha test in some conditions

That is, if there's no depth testing/writing, and the alpha equation will produce the same result as the alpha test (when the alpha test is >= 0 or != 0 and the blend func is safe), we turn off the alpha test.

Add some stats to get some idea of much alpha tested drawing we do.
...
Turns out it's one hell of a lot and we really should fix this by
checking both vertices and textures to deduce when we can just skip
alpha testing safely, probably quite often.
I care about this because alpha testing drawing is very expensive
on some mobile chips.
