Runtime effects: Detect passthrough sample calls automatically

As explained, this is *very* conservative. It only works when the child
is sampled from within main, and using a direct reference to the coords
parameter. If that parameter is ever modified (even after being used),
the optimization doesn't happen. For most cases, this is fine.
