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
* Convert 'installTypesForPackge' refactor to a suggestion
* Have checker collect a list of suggestion diagnostics instead of redoing work in calculateSuggestionDiagnostics
* Add comment
* Add diagnostic even with `--allowJs`
* Have getNameOfSymbolAsWritten quote nonidentifier nonnumeric symbols all the time
* Revert checker changes
* Reuse synthetic origin to indicate that derived declaration name may need to be quoted
Previously, this would assert:
```ts
exports.undeclared.n = 1;
```
Because undeclared was never declared in any recognised way. Now it no
longer asserts, but does not bind. That's because the full pattern
starts with the line `exports = require('./x')` and assumes that x.js
declares `undeclared`. I am not sure how to bind this. The new test
contains this pattern in case I figure it out.
* Add support for per-file jsx pragmas
* Add error for using jsx factory pragma with fragments
* More tests, use different regex class for pragma capture
* Unify all pragma parsing machinery
