    c++/reflection: ICE in get_reflection on INDIRECT_REF [PR125759]

    We crash here in outer_var_p on:

      /* These should have been stripped or otherwise handled by the caller. 
*/
      gcc_checking_assert (!REFERENCE_REF_P (decl));

    because we never stripped the INDIRECT_REF in get_reflection.  I don't
    think stripping it only for the outer_automatic_var_p call would be
    right so I'm doing it at the top of the function.

            PR c++/125759

    gcc/cp/ChangeLog:

            * reflect.cc (get_reflection): Do STRIP_REFERENCE_REF.

    gcc/testsuite/ChangeLog:

            * g++.dg/reflect/expr17.C: New test.
