Log:
        PR c++/88196 - ICE with class non-type template parameter.
        * pt.c (convert_nontype_argument): If the expr is a PTRMEM_CST, also
        check if the type we're converting it to is TYPE_PTRMEM_P.

        * g++.dg/cpp0x/ptrmem-cst-arg1.C: Tweak dg-error.
        * g++.dg/cpp2a/nontype-class10.C: New test.
        * g++.dg/template/pr54858.C: Tweak dg-error.
