    [PR42093] [arm] [thumb2] disable tree-dce for test

    CD-DCE introduces blocks to share common PHI nodes, which replaces a
    backwards branch that used to prevent the thumb2 jump table shortening
    that PR42093 tested for.  In order to keep on testing that the
    backward branch prevents the jumptable shortening, disable tree-dce.
