The __class__ cell used by zero-argument super() is now initialized from
type.__new__ rather than __build_class__, so class methods relying on that
will now work correctly when called from metaclass methods during class
creation. Patch by Martin Teichmann.

In f-strings, only allow backslashes inside the braces (where the
expressions are). This is a breaking change from the 3.6 alpha releases,
where backslashes are allowed anywhere in an f-string. Also, require that
expressions inside f-strings be enclosed within literal braces, and not
escapes like ``f'\x7b"hi"\x7d'``.
