Fix adjusts code to retain range check CastII nodes after loop opts until the end of optimizations, removing them at the end of all optimizations to avoid performance regressions. Ran GHA Sanity Checks, local Tier 1 and 2, and new `test/hotspot/jtreg/compiler/rangechecks/TestArrayAccessAboveRCAfterRCCastIIEliminated.java` tests. Patch is clean.
