* Use function instead of macro

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.

If a color buffer is still attached and is smaller than depth buffer,
the latter won't be fully cleared.
As a faster alternative, use GL4.4 clear texture function. Avoid to fiddle with

Until AMD release the driver with a fix, I can't use 2nd blending source with SSO.

than an uninitialized alpha value.

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.
