    c++: aggregate prvalue as for range [PR106230]

    Since my PR94041 work on temporary lifetime in aggregate initialization=
, we
    end up calling build_vec_init to initialize the reference-extended
temporary
    for the artificial __for_range variable.  And build_vec_init uses
    finish_for_stmt to implement its loop.  That function assumes that if
    __for_range is in current_binding_level, we're finishing a range-for, a=
nd
we
    should fix up the variable as it goes out of scope.  But when called fr=
om
    build_vec_init we aren't finishing a range-for, and do_poplevel doesn't
    remove the variable from scope because stmts_are_full_exprs_p is false.=
  So
    let's check that here as well, and leave the DECL_NAME alone.

            PR c++/106230

    gcc/cp/ChangeLog:

            * semantics.cc (finish_for_stmt): Check stmts_are_full_exprs_p.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/range-for38.C: New test.=
