There is an encoding issue with using delta `Δ`, where the browser will attempt to detect the file encoding if the character set is not explicitly declared on a `<script/>` tag, and Chrome will find the `Δ` character and decide it is window-1252 encoding, which misinterprets the `Δ` character to be some other character that is not a valid JS identifier character
So back to the frog eyes we go.

Previously we defensively wrapped expressions in case they ran afoul of
precedence rules. For example, it would be easy to create the TS AST structure
Call(Ternary(a, b, c)), but might result in printed code of:
```
a ? b : c()
```
Whereas the actual structure we meant to generate is:
```
(a ? b : c)()
```
However the TypeScript renderer appears to be clever enough to provide
parenthesis as necessary.
This commit removes these defensive paraenthesis in the cases of binary
and ternary operations.

The `Δ` caused issue with other infrastructure, and we are temporarily
changing it to `ɵɵ`.
This commit also patches ts_api_guardian_test and AIO to understand `ɵɵ`.
