04ceb3d9bd Disallow JS/non-JS merge without crashing 
Note that the error location is misleading because it's reported inside
the merge step for the js initializer.

7826b38426 Apply 'no-unnecessary-initializer' lint rule (#22014) 
* Apply 'no-unnecessary-initializer' lint rule

Forbids `let`/`const` statements to be initialized to `undefined`, since that's the initial value by default anyway.
The auto-fixer also happened to remove two unnecessary `as number` casts in `src/harness/parallel/worker.ts`.

For historical data: to run with `--fix`, I modified the line in `Jakefile.js` that declared the `cmd` for running TSLint.

* Moved worker.ts type assertions to parameters

Much better comment preservation (#22141) 
* Retain comments on (and produce sourcemaps on) the equals token in initializers

* Improved comments/sourcemaps for await, yield, while, and for

* Retain comments on block curly-braces

* Emit comments for if statements

* Improved switch case comment emit

* Improve comment and sourcemap emit for try/catch, throw, and continue statements

* Improve sourcemap emit and comments for with statements

* More accurate sourcemaps+comments emit for new, typeof, void, and delete

* Improve comment emit for element access expressions

* Preserve more comments on imports and exports

* Make function a bit more defensive like other usages of emitTrailingCommentsOfPosition

* Support preserving comments within empty lists

* Handle leading comments of tokens, conditionally indent leading comments

* Stop heuristically sourcemapping tokens

When the transform was trivial it worked, but was unneeded, but when it was complex, it was brittle - best leave source mapping up to the transformers

* Fix unneeded +1

* Tighten up element access comments

* Handle comments on parenthesized expression tokens

* Fix nit
