clang -fsanitize=kernel-memory already replaces calls to memset/memcpy/memmove and their __builtin_ versions with __msan_memset/__msan_memcpy/__msan_memmove in instrumented files, so there is no need to override them. In non-instrumented versions we are now required to leave memset() and friends intact, so we cannot replace them with __msan_XXX() functions.
