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?

Comienza reproduciendo el ejemplo de async generator del issue e inspecciona cómo el compilador y el language-service gestionan las sentencias return en los generadores. El trabajo estará terminado cuando un return con valor en un generador produzca la advertencia prevista y el IDE ofrezca un codefix “Did you mean yield?”, con cobertura del comportamiento del ejemplo.
