gsdx ogl: don't rely on the Z value in m_vt

Value seems wrongly rounded and you can't distinguish 0xFFFF from 0xFFFE
Instead check that depth is constant for the draw call and the value from the vertex buffer

So uses 0xFFFE to enable ate_all_color_then_depth in 16 bits format too :)

gsdx ogl: new optimization to bypass the alpha test
...
In FB_ONLY mode the alpha test impacts (discard) only the depth value.
If there is no depth buffer, we don't care about depth write. So alpha
test is useless and we can do the draw with a single draw call and no program

gsdx ogl: implement another algo to handle alpha test
...
Fix rendering issue on letters on Kengo/burnout 3/...
Default algo will execute the alpha test in 2 passes. However due to blending
you can't handle accurately the color.
Fortunately for us, the rendering uses an always pass depth test so you
can execute first all the color rendering (which doesn't depends on the alpha test)
And then the depth part which depends on the alpha test.

gsdx ogl: move zbuffer emulation code into a dedicated function
...
* Code was factorized a bit with the help of max_z
* Add an extra optimization if test is ZTST_GEQUAL and min z value is
the biggest value. Z test will always be pass.
Note: due to float rounding (23 bits mantissa vs 24 bits depth) the test
is done against 0xFF_FFFE and not 0xFF_FFFF. It is wrong but GPU will
also use float so impact will be null.

gsdx ogl: update accurate DATE behavior
...
* Fast accurate DATE is always enabled, it was faster than standard DATE
* The less fast version is always enabled too. It is likely barely used
so perf impact will be small on few game that could hit this path.
Nice rendering has a higher priority
* The "slow" path will depends on the date option.
Note normally it isn't too slow (-10%) if GL_ARB_shader_image_load_store
is supported but AMD crimson is an epic fail.

gsdx-ogl: implement previous DATE optimization in a single shader pass
...
Faster :) Reduce further the cost of accurate date
The optimization will clear the stencil to 1. So all pixels will have a
single sample that pass both the depth & stencil test. No primitive
overlaps So the destination alpha test can be done directly in the
shader.

gsdx ogl: accelerate special case of accurate date.
...
Game often uses date to allow a single pixel pass. If this
use case is detected, stencil buffer will be cleared after first pixels
that pass both depth&stencil test.
It seems to reduce the load on the GPU.
Note: with the help of texture barriere, maybe we could implement the algo
with a single pass.
