GSDX: Removed the collapsing of ge/g and le/l alpha tests in the shader code and the supporting code in the C++. This was presumably intended to reduce the number of shaders needed but a) this was never actually implemented, b) a single developer will generally not mix the functionally equivalent (with a different AREF) greater/less than with greater/less than or equal to in GS techniques, c) it really wouldn't make much of a difference to performance anyway and d) it would make an experimental change I'm working with more complicated and slower. 

No change in functionality expected.
