Incorrect handling of kwargs when default values are present

[takeda]

I have a following code:

#! /usr/bin/env python

from typing import Any

def function(a, b, c=False, **kwargs):
	# type: (str, int, bool, **Any) -> None

	print "Got the following:", repr(a), repr(b), repr(c), repr(kwargs)

def main():
	# type: () -> None

	function('a', 2, **{'optional1': 1})

if __name__ == '__main__':
	main()

When I run it it produces this result:

$ ./test.py
Got the following: 'a' 2 False {'optional1': 1}

It looks like mypy thinks that the kwargs were passed as argument c which is incorrect:

$ ../py37/bin/mypy --python-executable ../py27/bin/python test.py
test.py:13: error: Argument 3 to "function" has incompatible type "**Dict[str, int]"; expected "bool"

The mypy version is 0.641

For mypy this is just a dictionary, even if it is just a literal, so this is a duplicate of #5382.

I looks like I mentioned wrong issue when closing, this is not a duplicate of #5382 but of #1969
