         * into separate per-variable starts, adding explicit ends
         * wherever a variable is replaced or moved, and collecting
         * these and all the other local variable "activity"
         * together into an output list (without the other insns).
         *
         * Note: As of this writing, this method won't be handed any
         * insn lists that contain local ends, but I (danfuzz) expect
         * that to change at some point, when we start feeding that
         * info explicitly into the rop layer rather than only trying
         * to infer it. So, given that expectation, this code is
         * written to deal with them.
