d2469c0e89 fix type for itertools.product (#2129)
Fixes #1850.

The fix was already applied to Python 2, but the typevar-based solution there
leads to "cannot infer value of type variable" in mypy. I used the following
script to check:

```python
from itertools import product

reveal_type(product([1]))
reveal_type(product([1], ['x'], [False], [3.0], [(1,)], [('x',)], [{1}], [{1: 2}], repeat=5))
```

6c1dffed58 Make islice start and stop parameters optional (#2031)
From the documentation [1]: "If start is None, then iteration starts at zero."

[1] https://docs.python.org/3/library/itertools.html#itertools.islice.

PR #1603 made this change for Python 2.

5d1aacfed3 special-case overload for itertools.product with 'repeat' (#1410)
Add an additional overload for the `repeat = n` case. Since we don't know 
the numeric value of `repeat`, this just produces an iterator over an 
arbitrary-length tuple.

8d8a34cb83 Patch from @sfreilich: make itertools.ifilter predicate parameter Optional (#1257)
From Samuel Freilich:
In Python 2, the predicate parameter in itertools.ifilter and
itertools.ifilterfalse can be None, indicating that true or false values
should be retained (functionally equivalent to passing "bool" as the
predicate). In Python 3, filter and itertools.filterfalse have
the same behavior.

62efd05201 Add support for 6-ary izip and generic n-ary case
Using izip with up to 6 arguments will retain the arguments' type information,
using izip with 7 and more arguments will discard type information about the
generated tuple items.
