192** Calls an order tag method.
193** For lessequal, LUA_COMPAT_LT_LE keeps compatibility with old
194** behavior: if there is no '__le', try '__lt', based on l <= r iff
195** !(r < l) (assuming a total order). If the metamethod yields during
196** this substitution, the continuation has to know about it (to negate
197** the result of r<l); bit CIST_LEQ in the call status keeps that
198** information.
