JDK-8140405 - CompilerControl: Compiler.clear_directives doesn't clears the exclude state
Description
The test generates a random number of compiler directives, which might be greater than the value of CompilerDirectivesLimit. This causes the VM to stop execution upon the corresponding capacity check.

Fix: set CompilerDirectivesLimit to the max random number used.
Comments
Test bugfix also works for JDK11u. Applies cleanly. However, there are related issues (see above).
