Andrey Semashev 5777e9944b Added conversion from postfix increment proxy to iterator type. ...

This allows expressions such as `Iterator it2(it1++)` to compile.

Additionally separated operations that are allowed on the result of
dereferencing the proxy to a separate set of proxies to make the allowed
set of expressions more strict and unambiguous. In particular, it means
`it++` cannot be converted to value type and `*it++` cannot be converted
to the iterator type anymore. Also, make sure `*it1++ = *it2++` works
as expexted by explicitly converting the proxy to the value type on
assignment.
