False-positive `unreachable` code for empty generator

[cdce8p]

The most efficient way to create a empty generator is to add yield after return. pylint should not add the warning unreachable code for it. https://stackoverflow.com/a/61496399

Steps to reproduce

def func():
    return
    yield

Current behavior

test.py:3:4: W0101: Unreachable code (unreachable)

Expected behavior

No warning
