* Revert "Revert "Explicitly typed prototype assignments are context sensitive (#25688)""
This reverts commit ff8c30d636.
* Initial, wasteful, solution
It burns a check flags. Probably necessary, but perhaps not.
I haven't accepted baselines, but they are a bit questionable. I'm not
sure the synthetic type is right, because I expected to see
{ "exports": typeof import("x") } but instead see { "x": typeof
import("x") }.
* Update some baselines
* module.exports= always uses lhs type
Conflicts between exports property assignments and exports assignments
should get a union type instead of an error.
* Fix lint and accept good user baselines
* Add tests based on user tests.
These currently fail.
* Fix all but 1 of user test bugs found by typing module.exports
Still quite messy and full of notes
* Follow merged symbols+allow any object type
This allows exports like `module.exports = new EE` to have properties
added to them.
Still messy, but I'm going to run user tests and look for regressions.
* Update improved user baselines
* Fix infinite recursion when checking module.exports
* Fix bogus use-before-def error
getExportSymbolOfValueSymbolIfExported should always merge its returned
symbol, whether it's symbol.exportSymbol or just symbol.
* Update user test baselines
* Cleanup
* More small cleanup
* Bind `module` of `module.exports` as a special symbol
Previously it was also special, but created during name resolution in
the checker. It made sense when there was only one special symbol for
all files, but now there is one `module` symbol per file.
* Explicitly typed prototype assignments:ctx sensitive
Follow up to #25619: Add the necessary code to type `prototype`
correctly in prototype assignments so that code like
`F.prototype = { ... }` properly makes the object literal context
sensitive.
* Fix lint
* Explicitly typed js assignments: context sensitive
Explicitly typed special assignments should be context sensitive if they
have an explicit type tag. Previously no special assignments were
context sensitive because they are declarations, and in the common,
untyped, case we inspect the right side of the assignment to get the
type of the left side, and inspect the right side of the assignment to
get the type of the left side, etc etc.
Note that some special assignments still return `any` from
checkExpression, so still don't get the right type.
Fixes#25571
* Change prototype property handling+update bselines
* Fix indentation in test
* Update baselines
