7140924: SIGSEGV in compiled code for sun.awt.X11.XDecoratedPeer.updateMinSizeHints

Bytecode Escape Analyzer incorrectly reports that a method returns only new 
allocation even if it may also return NULL or Constant Pool pointers. It happens 
because bc analyzer uses empty_map for such constants. Use unknown_obj instead.

Verified with failed test.

Thanks,
Vladimir
