RFR: 8341649: Regressions with large metaspace apps after 8338526

[Coleen Phillimore]

Putting generated LambdaForm$MH and $DMH in non-class space seems to cause excess dependency checking for c2 compiled code and shows a performance regression in a new JMH performance test for MethodHandles (to be checked in at a later time).

When I made this abstract rather than final, I thought there were a many generated classes but I haven't found in testing more than a small percentage.  For example, Dacapo xalan there are 43/1000 classes that are these generated classes.  In Eric's new JMH test, it was more like 51/681.  Special casing "AllStatic" classes to go in non-class metaspace is a bit too risky at this time.  If it does become a problem with limited class metaspace, we can create another attribute to use.

Tested with tier1-4 and the JMH test.  Thanks Eric Caspole for finding this and all the testing.
