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.

gsdx-ogl: make VS more generic
...
Texture coordinate could be dummy/float/int integral/int normalized.
Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported
New behavior:
* Always compute all formats
* FS will be in charge to select the good format
Impact:
* VS will be slightly slower but it reduces shaders permutation from
little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
the GPU
* In future we could directly use the integral format in the FS.

The hack relies on the undefined behavior of the hardware so it can

This new hack drops the cache flusing when only the alpha channel is masked.
Alpha is a direct copy of the fragment. Normally masked bits will be constant
everywhere (RT, FS output, texture cache) so it would likely work.
Just in case, code is only enabled with the new shiny hack
