* Implement constructor type guard
* Fix code review issues for constructor type guard.
- Do not limit constructor expression to only identifiers
- Fix `assumeTrue` and operator no-narrow check
- Use better way to check that identifier type is a function
- Loosen restriction on what expr is left of ".constructor"
- Update typeGuardConstructorClassAndNumber test to include else cases
* Fix grammar & spacing in `narrowTypeByConstructor`
* fix bad merge
* switch (back?) to crlf
* update baselines

Use `emit()` for writing `questionDotToken`, leading to properly calling
the emit hooks (which `emitTokenWithComment` doesn't) and printing the
comments. This fixes#35372 by calling its hooks to set the `.__pos`
and `.__end` fields.
Also, remove `getDotOrQuestionDotToken` which was used only here --
mainly because it seems likely to encourage misusing the
`questionDotToken` again.
Also, fix a bunch of `visitor` -> `tokenVisiton` calls in
`visitorPublic.ts`.
* Reinterpret a type parameter constrained to any as an upper bound constraint
* Use real constraqint in alias in test

No error on `this` expressions in static property declaration
initialisers when targetting ESNext and with useDefineForClassFields. In
this case the emit is correct and the types are correct, so the error
should not be issued.
* Unwrap substitutions both before _and_ after potential simplification
* Repeatedly unwrap/simplify until no more can be performed
* Use seperate loops for source and target to reduce redundant calls
* Move loop into function
* Inline worker
* Properly handle control flows from returns in try/catch within IIFE
* Accept new baselines
* Add tests
* Accept new baselines
* When end of finally is unreachable, end of try statement is too
* Add additional test case
* use getters to define live export bindings
* fix scoping in export* helper
* Object.defineProperty cannot be used in ES3 target
* Accept changed baselines
* Use function expression, not arrow function
* Update importStarHelper to match export helper in binding-making
* Fix whitespace
* Adjust whitespace in edited helpers
* Use new helper for setting bindings, use unscoped __exportStar helper for exports so helpers get reused more
* Accept updated baselines
* Use __createBinding for individual reexports when target is es3
* Remove unneeded type assertion
* Singeline the helpers
* Add check for createBinding helper, accept updated baselines with shortened helper

Previously subtypes of Error extended Error, but the matching subtypes
of ErrorConstructor did not extend ErrorConstructor. The members in
es5.d.ts are identical, so there's no need except for allowing interface
merging into ErrorConstructor to affect subtypes as well.
* Allow `infer` type variables to have constraints infered and allow the breakdown of substitutes in simplifiable source inferences
* Still skip conditional inference when `extends infer Q` so such a pattern still acts as a constraint size breaker
* WIP
* Test no longer crashes, but emit trampoline is incomplete and skips pipeline phases
* Fix lints, use non-generator trampoline in emit (still skips pipeline)
* Final version with emitBinaryExprssion work stack that is only used if possible
* Fix lints
* retarget to es2015 for testing
* Use bespoke state machine trampolines in binder and checker
* Remove now extraneous code in parser
* Adjust fixupParentReferences to use a depth first preorder traversal rather than breadth first
* Reintroduce incremental fast bail in fixupParentReferences
* Revert target to es5
* PR feedback
* Small edit for devops rebuild with updated definition
* Fix comment nits, add internally extraneous check back into transformer
