This tries to fix PR30911 <http://llvm.org/PR30911>

This is an ad-hoc fix suggested by Eli Friedman. The problem might deeper in that the `CallResource` dependency is not correctly unscheduled. More details in that bug report. It would be nice if someone with more expertise with the SelectionDAG could have a look.
