See `nmethod::cleanup_inline_caches_impl`. It does verification per callsite, and does the whole thing during parallel GC cleanup, which is STW at least in G1. This gets expensive for CTW scenarios. We should wrap that under the same flag introduced by [JDK-8360867](https://bugs.openjdk.org/browse/JDK-8360867).
