Bug: InterfaceMethodref for invokespecial must name a direct superinterface
https://bugs.openjdk.java.net/browse/JDK-8026065

Summary of fix:
    Add verification to check that invokespecial names a method in a 
direct superinterface
    of the current class or interface.  See (JVMS draft 0.6.3) 4.9.2 
Structural Constraints,
    "Each invokespecial instruction must name an instance initialization 
method (2.0) or
      must reference a method in the current class or interface, a 
method in a superclass of the
      current class or interface, or a method in a direct superinterface 
of the current class or interface."

Tests:
     jtreg hotspot/test/*, JDK java.lang & java.util, JCK vm & lang,

Thank you, Lois
