New description:
cythonize `lazy_attribute` so that it provides acceptable performance on
cython classes that don't have a `__dict__` but do have a
`__cached_methods` dictionary.
In the current design, we let `lazy_attribute` inherit from a `cdef class`
`_lazy_attribute` that implements all the time-critical stuff (including a
`cdef` slot for `__name__`). `lazy_attribute is a conventional class so
that we can override documentation and module on it, which was previously
done for introspection reasons. This inheritance construction seems to
have minimal runtime consequences.
