Enhancement: add support for cross-specialization boundaries accessors.
* use specialized host class when emitting invokespecial generic call sites
* fix missing specialization of receiver type in the BSM args of generic calls indy
* workaround: relax access MH constant-related checks on anonymous class (coming from UNSAFE.dAC)
