    [PR107170] Avoid copying incompatible types in legacy VRP.

    Legacy VRP is calling ranger deep inside the bowels, and then trying to
    copy an incompatible type.  My previous patch in this area assumed that
    the only possibility out of vr_values::get_value_range for an
    unsupported type was VARYING, but UNDEFINED can also be returned.

            PR tree-optimization/107170

    gcc/ChangeLog:

            * vr-values.cc (vr_values::range_of_expr):  Do not die on
            unsupported types.

    gcc/testsuite/ChangeLog:

            * gcc.dg/tree-ssa/pr107170.c: New test.=
