The error message would have been emitted from
expand_builtin___clear_cache and maybe_emit_call_builtin___clear_cache
 would not have been called from user code.
All other uses of maybe_emit_call_builtin___clear_cache are internal
to gcc and should have the correct mode so asserting is the right
thing to do.
