* Optimize intersections of unions of unit types * Add regression test * Accept new baselines * LEGO: check in for master to temporary branch. * Add Unicode ThirdPartyNotice * Properly handle edge cases * Sort the whole diagnostic, plus giving up on isolating tests (#24186) * Sort the whole diagnostic * Also strip references to our repos node_modules, since removing it is hard * LEGO: check in for master to temporary branch. * add quick fix for import type missing typeof * Add callback tag, with type parameters (#23947) * Add initial tests * Add types * Half of parsing (builds but does not pass tests) * Parsing done; types are uglier; doesn't crash but doesn't pass * Bind callback tag Builds but tests still don't pass * Only bind param tags inside callback tags * Fix binding switch to only handle param tags once * Checking is 1/3 done or so. Now I'm going to go rename some members to be more uniform. I hate unnnecessary conditionals. * Rename typeExpression to type (for some jsdoc) (maybe I'll rename more later) * Rename the rest of typeExpressions Turns out there is a constraint in services such that they all need to be named the same. * Few more checker changes * Revert "Rename the rest of typeExpressions" This reverts commit f41a96b. * Revert "Rename typeExpression to type (for some jsdoc)" This reverts commit 7d2233a. * Finish undoing typeExpression rename * Rename and improve getTypeParametersForAliasSymbol Plus some other small fixes * Core checking works, but is flabbergastingly messy I'm serious. * Callback return types work now * Fix crash in services * Make github diff smaller * Try to make github diff even smaller * Fix rename for callback tag * Fix nav bar for callback tag Also clean up some now-redundant code there to find the name of typedefs. * Handle ooorder callback tags Also get rid of redundant typedef name code *in the binder*. It's everywhere! * Add ooorder callback tag test * Parse comments for typedef/callback+display param comments * Always export callbacks This requires almost no new code since it is basically the same as typedefs * Update baselines * Fix support for nested namespaced callbacks And add test * Callbacks support type parameters 1. Haven't run it with all tests 2. Haven't tested typedef tags yet 3. Still allows shared symbols when on function or class declarations. * Template tags are now bound correctly * Test oorder template tags It works. * Parser cleanup * Cleanup types and utilities As much as possible, and not as much as I would like. * Handle callback more often in services * Cleanup of binder and checker * More checker cleanup * Remove TODOs and one more cleanup * Support parameter-less callback tags * Remove extra bind call on template type parameters * Bind template tag containers Doesn't quite work with typedefs, but that's because it's now stricter, without the typedef fixes. I'm going to merge with jsdoc/callback and see how it goes. * Fix fourslash failures * Stop pre-binding js type aliases Next up, stop pre-binding js type parameters * Further cleanup of delayed js type alias binding * Stop prebinding template tags too This gets rid of prebinding entirely * Remove TODO * Fix lint * Finish merge with use-jsdoc-aliases * Update callback tag baselines * Rename getTypeParametersForAliasSymbol The real fix is *probably* to rename Type.aliasTypeArguments to aliasTypeParameters, but I want to make sure and then put it in a separate PR. * moveToNewFile: Don't move imports (#24177) * Reduce map lookups (#24203) * Fix jsdoc type resolution [merge to master] (#24204) * Fix JSDoc type resolution Breaks type parameter resolution that is looked up through prototype methods, though. I need to fix that still. * Check for prototype method assignments first * Undo dedupe changes to getJSDocTags * JS Type aliases can't refer to host type params Previously, js type aliases (@typedef and @callback) could refer to type paremeters defined in @template tags in a *different* jsdoc tag, as long as both tags were hosted on the same signature. * Reduce dedupe changes+update baseline The only reason I had undone them was to merge successfully with an older state of master. * Add undefined guard * moveToNewFile: Fix bug for VariableDeclaration missing initializer (#24214) * Use import types to refer to declarations in declaration emit (#24071) * Stand up a simple implementation using import types for exports of modules which are otherwise inaccessible * Ensure references exist to link to modules containing utilized ambient modules * Accept baselines with new import type usage * Fix lint * Accept changed baseline (#24222) * fixUnusedIdentifier: Don't delete node whose ancestor was already deleted (#24207) * More robust circularity detection in node builder (#24225) * Improve ChangeTracker#deleteNodeInList (#24221) * moveToNewFile: Fix bug for missing importClause (#24224) * Set startPos at EOF in jsdoc token scanner so node end positions for nodes terminated at EoF are right (#24184) * Set startPos at EOF in jsdoc token scanner to node end positions for nodes terminated at EoF are right * More complete nonwhitespace token check, fix syntactica jsdoc classifier * Use loop and no nested lookahead * Do thigns unrelated to the bug in the test * Fix typo move return * Patch up typedef end pos * Fix indentation, make end pos target more obvious

Namely also checking for circularity involving just the constructor side, rather than only detecting circular instances.
Fixes #24194
