5810765259 Emit defineProperty calls before param prop assignments
Note that I restricted this to --useDefineForClassFields is true.
Nothing changes when it's off. I think this is the correct fix for a
patch release.
However, in principal there's nothing wrong with moving parameter
property initialisation after property declaration initialisation. It
would be Extremely Bad and Wrong to rely on this working:
```ts
class C {
p = this.q // what is q?
constructor(public q: number) { }
}
```
But today it does, and probably somebody relies on it without knowing.

8ae5a8cfce useDefineForClassFields skips emit of ambient properties
Previously:
```ts
class C {
declare p
}
```
would incorrectly emit
```js
class C {
constructor() {
Object.defineProperty(this, "p", {
enumerable: true,
configurable: true,
writable: true,
value: void 0
});
}
}
```
when useDefineForClassFields was turned on (for targets <ESNext).

62aad54b98 Fix a crash when transforming functions in modules.
When transforming a module declaration and block, parse tree nodes
contained in the module block have their parent pointers reset due to
`shouldEmitModuleDeclaration` calling into `isInstantiatedModule`, which
needs to set parent pointers to operate.
That causes a crash when later transforming any nodes within the module,
as retrieving their source file in `getSourceFileOfNode` (via
`getOrCreateEmitNode`) fails, due to their new synthesized parent nodes
not being in a source file.
This change avoids the issue by using the parse tree node in `ts.ts` to
decide whether a module declaration should be emitted (i.e. whether the
module contains values).
This means transformers cannot add values to modules that previously did
not contain any.
Fixes#34644.

2e0b4513ef 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 #33213Fixes#34762 (by reverting #33213)

ab9bc3a55a Fix type reference to merged prototype property assignment
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

97dcbd3bb9 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.

Component commits:
056a656937 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.
