RFR (S) 8181171: Deleting method for RedefineClasses breaks ResolvedMethodName

8210457: JVM crash in ResolvedMethodTable::add_method(Handle)
Summary: Add a function to call NSME in ResolvedMethodTable to replace 
deleted methods.

This Unsafe.throwX trick is also used for vtable initialization for 
throwing IllegalAccessError.  Tested with redefinition tests in the 
repository and tier1-3, and added tests.
