Optimize out no-op `yield from` statements
If the array is empty, then I'd expect that the generator is never left,
and that can be converted to a no-op and the return value would always be `null`.
Make `yield from [];` as efficient as `if (false) { yield null; }`
when opcache's sccp pass is enabled.
Closes GH-5679
