    c++: ICE with defaulted comparison operator [PR94478]

    Here we ICE because early_check_defaulted_comparison passed a null
    ctx to same_type_p.  The attached test is ill-formed according to
    [class.compare.default]/1, so fixed by detecting this case early.

            PR c++/94478 - ICE with defaulted comparison operator
            * method.c (early_check_defaulted_comparison): Give an error when
the
            context is null.

            * g++.dg/cpp2a/spaceship-err4.C: New test.
