2766 favor of the fold_for_warn within warn_for_memset.
2767 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
2768 param, defaulting to false. Convert "expr" to a cp_expr, and call
2769 maybe_add_location_wrapper on it when wrap_locations_p is true.
2770 (cp_parser_unary_expression): Call maybe_add_location_wrapper on
2771 the result for RID_ALIGNOF and RID_SIZEOF.

2799 * call.c (maybe_warn_class_memaccess): Add forward declaration.
2800 Change last argument from tree * to const vec<tree, va_gc> *, adjust
2801 args uses and check number of operands too. Don't strip away any
2802 nops. Use maybe_constant_value when looking for INTEGER_CST args.
2803 Deal with src argument not having pointer type. Check
2804 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
2806 (build_over_call): Call maybe_warn_class_memaccess here on the
2808 (build_cxx_call): Rather than here on converted arguments.

2819 * constexpr.c (cxx_eval_statement_list): Ignore DEBUG_BEGIN_STMTs
2820 in STATEMENT_LIST. Remove unneeded assert.

2839 * typeck.c (build_static_cast_1): For static casts to reference types,
2840 call build_base_path with flag_delete_null_pointer_checks as nonnull
2841 instead of always false. When -fsanitize=null, call
2842 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
2843 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
2844 call if the first argument is INTEGER_CST with REFERENCE_TYPE.

2871 * tree.c (replace_placeholders_r): Pass NULL as last argument to

2874 to false and return.
