gallium: add condition parameter to render_condition
For conditional rendering this makes it possible to skip rendering
if either the predicate is true or false, as supported by d3d10
(in fact previously it was sort of implied skip rendering if predicate
is false for occlusion predicate, and true for so_overflow predicate).
There's no cap bit for this as presumably all drivers could do it trivially
(but this patch does not implement it for the drivers using true
hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL
functionality).
