clang-format supports vim built with python3
clang-format supports vim built with python3

1. The 2016 version clang-format instructions are for Python2 Vim. If
your Vim has only Python3 or if you load Python3 before Python2, those
instructions won't work.

2. To make `clang-format` work, we need to upgrade `clang-format` to
2018 Aug version or later

3. Accordingly, we need to update the way we invoke `clang-format.py`

4. Refer to https://reviews.llvm.org/D23319 for details
