[Bug c++/125797] [reflection] Faulty immediate-escalation with std::meta::current_function, templates, and 'requires' clause

--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
build_invoke already correctly sets:

  /* INVOKE is an unevaluated context.  */
  cp_unevaluated cp_uneval_guard;

but that is reset to 0 in instantiate_body:

   bool push_to_top = maybe_push_to_top_level (d);

so when folding we do promote.
