dd1ef88d01 Use control flow to type CommonJS exports (#42751)
* Allow redeclaring CommonJS alias with initial undefined

This allows us to read our own output, plus the times when people
manually write exactly the same pattern.

Fixes #40555

* Use control flow to type commonjs exports

1. Could probably use a *lot* more tests.
2. getTypeOfAlias redoes some work from resolveAlias because it needs to
not resolve the alias completely, just to its export.

* fix lint, improve jsdoc

* Add tests, improve+fix control flow

1. Update the module.exports test to match the exports ones.
2. Add a test of evolving commonjs type.
3. Add a test of assignment as last statement.

(1) exposed a bug that required a better synthetic reference. (3)
exposed a bug that was most easily fixed by giving source files a
`endFlowNode` like functions and setting it in the binder.

* fix lint

76a2ae3d69 Only issue matching token errors on non-dupe locations (#43460)
* Only issue matching token errors on non-dupe locations

Intead of unconditionally retrieving the last error and attaching a
related span, `parseErrorAt` and friends now return the last error and
return `false` when there is none.

Also make one more place use parseExpectedMatchingBrackets that I missed
last time.

* Inline parseTokenForError, return undefined not false

* skip redundant undefined assignment
