Fix clamping to the correct texel.

This fixes things when edges bleed in from a larger framebuffer. We need
to clamp to the internal texels of the range.

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.
