    c++: Fix ICE with nullptr comparison (GCC 11) [PR101592]

    On trunk, PR101592 was fixed by r12-2537, but that change shouldn't be
    backported to GCC 11.  In the PR Jakub suggested this fix, so here it
    is, after the usual testing.

            * fold-const.c (make_range_step): Return NULL_TREE for
NULLPTR_TYPE.
