This may be not enough. I just fixed the issue in premain for aarch64 after https://bugs.openjdk.org/browse/JDK-8358329 :
https://github.com/openjdk/leyden/commit/2c69aa27ee88cca0c85ab275b4b5f24035ecf4d6

The issue was that `ICache::invalidate_range()` was called only for part of AOTed stub code based `static_call_stub_size()` which could be smaller in production run.

In short, in "production" run we need to know what code we are working on/patching: AOTed or normal JITed.
