* cvt.c (cp_convert_to_pointer): Warn for zero as null pointer
constant.
* typeck.c (cp_truthvalue_conversion): Handle pointers and member
function pointers under c_inhibit_evaluation_warnings; use
nullptr_node for data member pointers.
(cp_build_binary_op): Tweak, just forward to cp_convert op1,
either a nullptr_node or an integer_zero_node.
(build_ptrmemfunc): Use nullptr_node.
* init.c (build_zero_init_1): Likewise.
