4283 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
4284 param, defaulting to false. Convert "expr" to a cp_expr, and call
4285 maybe_add_location_wrapper on it when wrap_locations_p is true.
4286 (cp_parser_unary_expression): Call maybe_add_location_wrapper on
4287 the result for RID_ALIGNOF and RID_SIZEOF.

4315 * call.c (maybe_warn_class_memaccess): Add forward declaration.
4316 Change last argument from tree * to const vec<tree, va_gc> *, adjust
4317 args uses and check number of operands too. Don't strip away any
4318 nops. Use maybe_constant_value when looking for INTEGER_CST args.
4319 Deal with src argument not having pointer type. Check
4320 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
4322 (build_over_call): Call maybe_warn_class_memaccess here on the
4324 (build_cxx_call): Rather than here on converted arguments.

4335 * constexpr.c (cxx_eval_statement_list): Ignore DEBUG_BEGIN_STMTs
4336 in STATEMENT_LIST. Remove unneeded assert.

4356 call build_base_path with flag_delete_null_pointer_checks as nonnull
4357 instead of always false. When -fsanitize=null, call
4358 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
4359 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
4360 call if the first argument is INTEGER_CST with REFERENCE_TYPE.

4390 to false and return.
