[m-dev.] diff: fix arg_order_rearrangement test case

[Fergus Henderson]

Estimated hours taken: 0.25

tests/warnings/Mmakefile:
	Pass `--excess-assign --common-struct' to mmc for the
	arg_order_rearrangement test case, since without it you don't
	get any accumulator introduction in this test case, and so you
	don't get the warning.  Note that `--common-struct' is not
	actually doing any common structure elimination for this test
	case, but it is needed because it has the effect of removing
	some unnecessary assignments that `--excess-assign' doesn't
	remove.
