ART: Run RTP if invoke inputs have more specific type

Moving RTP inside the graph builder introduced a regression where
replacing the inner parameters with the actual arguments of the
HInvoke would not build the inner graph with types more specific
than the method's signature.

This patch runs RTP on the inner graph again when it is detected
that RTP may improve typing precision.
