Log:
    Core DR 342
    PR c++/48582
    * pt.c (check_valid_ptrmem_cst_expr): A null member pointer value
    is valid in C++11.
    (convert_nontype_argument): Likewise.  Implicitly convert nullptr
    and do constant folding.
    * mangle.c (write_template_arg_literal): Mangle null member
    pointer values as 0.
    * call.c (null_member_pointer_value_p): New.
    * cp-tree.h: Declare it.
