GSdx-d3d: Update Fast DATE and Alpha Stencil behaviour. 

Idea is to allow Alpha Stencil to work with Fast Date.
Let Fast Date run for the supported calls since it's more accurate, let
Alpha Stencil take care of the rest.

This might fix some issues where Alpha Stencil caused some issues making
it a bit more accurate.
