RFR(S): 8228839: Non-CFG nodes have control edges to calls, instead of the call's control projection

This is a workaround for the problem that sometimes non-CFG nodes have 
their ctrl (PhaseIdealLoop::get_ctrl(n)) set directly to calls, instead 
of the call's control projection. I'm working on a patch for that, but 
it might end up a bit intrusive. This is a workaround that simply checks 
and adjusts for that case.
