[8u] RFR + RFA: 8188223: IfNode::range_check_trap_proj() should handler dying subgraph with single if proj

We (Red Hat) would like to backport 8188223 to 8u: we're hitting hit
with openJFX. The patch doesn't apply cleanly. See below for a new
webrev. It was pushed to jdk10 5 months ago and there was no follow up
bugs that I'm aware of.
