llvmpipe: fixes for conditional rendering
honor render_condition for clear_render_target and clear_depth_stencil. Also add minimal support for occlusion predicate, though it can't be active at the same time as an occlusion query yet. While here also switchify some large if-else (actually just mutually exclusive if-if-if...) constructs. Reviewed-by: Jose Fonseca <jfonseca@vmware.com>
