please review the following patch:
JDK-8151573 introduced multiversioning for range check elimination. Explicitly turning of range check elimination now crashes the VM with an assert in PhaseIdealLoop::has_range_checks() because we assume that this is only called if range check elimination is enabled.
I think we should disable multiversioning if range check elimination is turned off. I added the corresponding check.
Tested with regression test and RBT (running).
