Small optimization for Disable Alpha Test - makes sure we don't generate the same shader twice.

Add ugly hack setting for PowerVR to disable alpha test
...
Causes glitches but the speedup is truly massive in some games so I relent :/
Please do not report graphics bugs when this is enabled...
Future: Maybe remove this setting except on PowerVR?

PowerVR: work around what appears to be a driver bug with equality test + discard, but not completely sure that discard isn't just broken.

If this change breaks something, it was probably already broken, and it's PVR-only.

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.
