[Statepoints] Update DAG root after emitting statepoint.

Authored by dantrushin on Sep 7 2020, 11:22 AM.



Since we always generate CopyToRegs for statepoint results,
we must update DAG root after emitting statepoint, so that
these copies are scheduled before any possible local uses.
Note: getControlRoot() flushes all PendingExports, not only
those we generates for relocates. If that'll become a problem,
we can change it to flushing relocate exports only.
