Dead return statements in a generator should offer a did-you-mean-yield codefix

TypeScript Version: 3.0.0-dev.201xxxxx

Search Terms: yield return generator

Currently it is possible to have the following code:
Code

async function *myGeneratorFunction(): AsyncIterableIterator<number> {
    return 1;
    return 2;
    return 3;
}

Expected behavior:
A generator function that yields numbers 1 - 3

Actual behavior:
No syntax/runtime error but due to a human mistake the generator function is useless.

I copy/pasted an existing generator function, deleted the body with the new implementation and mistakenly used return instead of yield.

It would be nice if TypeScript could warn when it's encountering a return with an actual value inside a generator function.
It makes no sense to return a value.
Could be combined with a codefix in the IDE: Did you mean yield?

Beginne damit, das async generator-Beispiel aus dem Issue zu reproduzieren, und untersuche die Behandlung von return-Anweisungen in Generatoren durch Compiler und language-service. Die Arbeit ist abgeschlossen, wenn ein wertbehaftetes return in einem Generator die beabsichtigte Warnung erzeugt und die IDE einen „Did you mean yield?“-Codefix anbietet, mit Abdeckung des Verhaltens des Beispiels.
