--- Comment #7 from Ilya Enkovich <enkovich.gnu at gmail dot com> ---
Right, wrong const attribute causes no VUSE for calls to the function which
leads to # VUSE <.MEM> generated for added loads and requires SSA update.

We may actually call update_ssa only in case of missing VUSE still allowing
optimization for functions wrongly marked as const.
