    tree-optimization/116079 - store motion and clobbers

    When we move a store out of an inner loop and remove a clobber in
    the process, analysis of the inner loop can run into the clobber
    via the meta-data and crash when accessing its basic-block.  The
    following avoids this by clearing the VDEF which is how it identifies
    already processed stores.

            VDEF of elided clobbers.
