	(simplify_plus_minus_op_data_cmp): For REGs, break ties on the regno.
	(simplify_plus_minus): Count n_constants while filling ops.  Replace
	qsort with insertion sort.  Before going through the array to simplify
	pairs, sort it.  Delay early exit until after the first sort, exiting
	only if no swaps occurred.  Simplify pairs in reversed order, without
	special-casing the first iteration.  Pack ops after simplifying pairs.
