Missed the spot when doing JDK-8360867. There is a path from GC that calls into IC verification when cleaning the caches. 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.

Motivational improvements:
