    Do not invoke SCEV if it will use a different range query.

    SCEV always uses the current range_query object.
    Ranger's cache uses a global value_query when propagating cache values =
to
    avoid re-invoking ranger during simple vavhe propagations.
    when folding a PHI value, SCEV can be invoked, and since it alwys uses
    the current range_query object, when ranger is active this causes the
    undesired re-invoking of ranger during cache propagation.

    This patch checks to see if the fold_using_range specified range_query
    object is the same as the one SCEV uses, and does not invoke SCEV if
    they do not match.
