2338 Change last argument from tree * to const vec<tree, va_gc> *, adjust
2339 args uses and check number of operands too. Don't strip away any
2340 nops. Use maybe_constant_value when looking for INTEGER_CST args.
2341 Deal with src argument not having pointer type. Check
2342 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless

2378 call build_base_path with flag_delete_null_pointer_checks as nonnull
2379 instead of always false. When -fsanitize=null, call
2380 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
2381 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
2382 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
