    [prange] Avoid looking at type() for undefined ranges

    Undefined ranges have no type.  This patch fixes the thinko.

            PR middle-end/115128
            * ipa-cp.cc (ipa_value_range_from_jfunc): Check for undefined_p

            (propagate_vr_across_jump_function): Same.

    gcc/testsuite/ChangeLog:

            * gcc.dg/tree-ssa/pr115128.c: New test.
