ccb08b9d - [libc++] Also provide an alignment assumption for vector in C++03 mode (#124839)

[libc++] Also provide an alignment assumption for vector in C++03 mode (#124839) There's no reason not to, and it's easy enough to do using enable_if. As a drive-by change, also add a missing _LIBCPP_NO_CFI attribute on __add_alignment_assumption.
