Incorrect 'dead catch' for catching exceptions that are thrown into generators

[jeroennoten]

Bug report

When using Generator::throw() feature, calling yield will actually throw that exception. Surrounding yield with a try...catch-block makes PHPStan with bleeding edge enabled incorrectly report a dead catch.

Code snippet that reproduces the problem

https://phpstan.org/r/f9c59ed6-949c-47bf-ae2d-69d3f3290842

If you add (new HelloWorld())->consumeGenerator(); to this example, and run it with PHP, you'll see that the exception message actually is echoed, which proves that this not a dead catch.

Expected output

No error.
