    c++/reflection: adjust error message
    
    Now that the condition includes all captures, let's not talk about
    init-capture.  Also print the decl.
    
    gcc/cp/ChangeLog:
    
            * reflect.cc (get_reflection): Adjust the error message for the
            is_capture_proxy check.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/reflect/expr6.C: Adjust dg-error.
