[jdk21u-dev] RFR: 8331088: Incorrect TraceLoopPredicate output

[Satyen Subramaniam]

Backporting JDK-8331088: Incorrect TraceLoopPredicate output. The PhaseIdealLoop::loop_predication_impl_helper prints the node index of the lower bounds check, rather than the upper bounds check (introduced by https://bugs.openjdk.org/browse/JDK-8203197).
