softgpu: Fix self-render detect in Ridge Racer.
...
When we flush we mark all pending writes zero, but we rely on this being
set to detect self-render.
TRANSFORM_ALL was wrong as well, sometimes clearing BINNER_RANGE.

If we don't need to write stencil on sfail/zfail, we can do the depthtest
early, which allows us to more often skip texture sampling.
