gsdx ogl: update accurate DATE behavior

Browse Source 
* 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.
