It's not a trivial change. So if tests that used to work start failing and this change is suspected, it will be as easy as running with -XX:-C1PatchInvokeDynamic to verify this change is the cause. I think it's a good idea to have this flag.

Here is a new webrev in case you want to check I split the right checks.
