    something that might cause the compiler to pop arguments to function
    calls (because those pops have previously been deferred; see
    INHIBIT_DEFER_POP for more details), use do_pending_stack_adjust
    before calling this function.  That will ensure that the deferred
    pops are not accidentally emitted in the middle of this sequence.  */
