    PHIOPT: Move check on diamond bb to tree_ssa_phiopt_worker from
minmax_replacement

    This moves the check to make sure on the diamond shaped form bbs that
    the the two middle bbs are only for that diamond shaped form earlier
    in the shared code.
    Also remove the redundant check for single_succ_p since that was already
    done before hand.
    The next patch will simplify the code even further and remove redundant
    checks.
