8199342 The constant pool forgets it has a Dynamic entry if there are overpass methods

Looks good. Thanks for catching this.

And redefineclasses goes through the ClassFileParser so should set the flag there.


p.s. thank you for the test. A note - I believe this code path is called for any class file
that requires an overpass due to default method processing. We create these to throw
a number of exceptions, such as IncompatibleClassChangeError (e.g. diamond shape
for default methods) or some of the AbstractMethodError cases.
