Enhancement: add support for anyfied wildcards in specializer
* all specialization share common (virtual interface) supertype
* add support for dynamic boxing/bridge generation
* add boostrap for virtual access on anyfied wildcards parameterized types
* Pipeline refactoring to take into account anyfied wildcards (contributed by: bgoetz at oracle.com)
* add simple anyfied pipeline test
* add several tests for anyfied wildcards accessors
