00dd1f0609 Add isIntersectionConstituent to relation key (#34789)
* Add isIntersectionConstituent to relation key

isIntersectionConstituent controls whether relation checking performs
excess property and common property checks. It is possible to fail a
relation check with excess property checks turned on, cache the result,
and then skip a relation check with excess property checks that would
have succeeded. #33133 provides an example of such a program.

Fixes #33133 the right way, so I reverted the fix at #33213
Fixes #34762 (by reverting #33213)
Fixes #33944 -- I added the test from #34646

* Update comments in test

7635884224 JSDoc type reference understands require with entity name (#34804)
* resolve require with entity name postfix

For example, `require("x").c`. This is the value equivalent of
`import("x").a.b.c`, but the syntax tree is not as nicely designed for
this purpose.

Fixes #34802

* Add bug number to test

* Add optional chain test

080e41dc90 Fix type reference to merged prototype property assignment (#34764)
The constructor function code path in the return type checking of
signatures needs to pass the *merged* symbol of the declaration to
getDeclaredTypeOfClassOrInterface. Other callers of
getDeclaredTypeOfClassOrInterface do this, or used an already-merged
symbol.

Fixes #33993

Fixes #33860 by making it an error.  This is an improvement, but sounds
like it would be better to make it work later.

a03227d60e Avoid a crash with @typedef in a script file. (#33847)
* Avoid a crash with `@typedef` in a script file.

Scripts (as opposed to modules) do not have a symbol object. If a script
contains a `@typdef` defined on a namespace called `exports`, TypeScript
crashes because it attempts to create an exported symbol on the
(non-existent) symbol of the SourceFile.

This change avoids the crash by explicitly checking if the source file
has a symbol object, i.e. whether it is a module.

* Add usage of exports.SomeName typedef.

* Fix bug at bind site rather than in declare func

d892fd408f Fix expando handling in getTypeReferenceType (#34712)
* Fix expando handling in getTypeReferenceType

getExpandoSymbol looks for the initialiser of a symbol when it is an
expando value (IIFEs, function exprs, class exprs and empty object
literals) and returns the symbol.

Previously, however, it returned the symbol of the initialiser without
merging with the declaration symbol itself. This missed, in particular,
the prototype assignment in the following pattern:

```js
var x = function x() {
  this.y = 1
}
x.prototype = {
  z() { }
}

/** @type {x} */
var xx;
xx.z // missed!
```

getJSDocValueReference had weird try-again code that relied on calling
getTypeOfSymbol, which *does* correctly merge the symbols. This PR
re-removes that code and instead makes getExpandoSymbol call
mergeJSSymbols itself.

* Remove extra newline

969634b97c Restore delayed merge check to getTypeFromJSDocValueReference (#34706)
* Restore delayed merge check to getTypeFromJSDocValueReference

This is needed when a function merges with a prototype assignment. The
resulting *merged* symbol is a constructor function marked with
SymbolFlags.Class. However, the merge doesn't happen until
getTypeOfFuncClassEnumModule is called, which, in the
getTypeReferenceType code path, doesn't happen until
getTypeFromJSDocValueReference. That means the check for
SymbolFlags.Class is missed.

Previously, getTypeFromJSDocValueReference had a weird check
`symbol !== getTypeOfSymbol(symbol).symbol`, which, if true, ran
getTypeReferenceType again on `getTypeOfSymbol(symbol).symbol`. For
JS "aliases", this had the effect of dereferencing the alias, and for
function-prototype merges, this had the effect of ... just trying again
after the merge had happened.

This is a confusing way to run things. getTypeReferenceType should
instead detect a function-prototype merge, cause it to happen, and
*then* run the rest of its code instead of relying on try-again logic at
the very end. However, for the RC, I want to fix this code by restoring
the old check, with an additional check to make sure that #33106 doesn't
break again:

```ts
const valueType = getTypeOfSymbol(symbol)
symbol !== valueType.symbol && getMergedSymbol(symbol) === valueType.symbol
```

I'll work on the real fix afterwards and put it into 3.8.
