[LLVM][TableGen] Notebook describing how to write a Python backend
This tutorial uses the dump json option to write a backend for
SQL queries.
It is based on the work of Min-Yih Hsu:
* https://github.com/mshockwave/SQLGen
* https://www.youtube.com/watch?v=UP-LBRbvI_U
I hope that having the same concepts in 3 forms will allow people
to choose the style that fits them.
The main drawback here being that it's in Python. C++ can be used
in a notebook (https://github.com/jupyter-xeus/xeus-cling) but I
decided against it for a few reasons:
* Python is the default for Jupyter, no extra installs needed.
* Having the code in a second language may help people who
know one or the other.
* There is no upstream example of a JSON powered backend.
(and although we would be unlikely to accept one upstream,
I think it's a great option for quick development before
translating into C++)
