-----------------------------+-------------------------------------
We further simplify QQbar code by:
- using python operator to indentify binary operators instead of strings.
In other words we replace `'+'` by `operator.add`, `'-'` by
`operator.sub`, etc
- writing only one function `binop` instead of `addsub` and `muldiv`.
- removing the method `kind` of descriptors and instead use the class
themselves for dispatching
- detect unions earlier in the code to avoid constructing `ANBinaryExpr`
