/* Begin emitting insns to a sequence.  If this sequence will contain
   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.  */
