Apply unsupported blending modes in the shader.
...
This handles unsupported fixed color combinations, alpha doubling, etc.
Where possible, tries to avoid it - it means using a blit (without the
framebuffer fetch extension), which can slow things down a lot with tons
of drawcalls.

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.)

Optimize ComputeFragmentShaderID() a bit.

I've seen it decently high on some profiles (1-2%). This cuts it down by
12.5% when used in a tight loop. The temporary was 8%, the ifs were the
other 4.5%.

Optimize > and != 0 alpha tests.

There's no need to do rounding in this case. These are very common.
Also, if the test was !=, convert it to >, which may work better on
PowerVR.

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.
