The test was failing on 32-bit targets because of the different size of
`dereferenceable` attribute.

```
The size of coroutine buffer passed as the first argument to the
"modify" coroutine function is dependent on the target pointer size.
(it's calculated as `NumWords_YieldOnceBuffer` * sizeof(void*)`).
The size is out of the scope of the test, so just accept any size.

@swift-ci Please smoke test |

I already have a fix for this in #70929, can you check if that would work instead? |

@finagolfin The test fix is almost identical to yours, but the CMake change seems arguable. I want to merge this PR to unblock our CI first, and the CMake change should be discussed in your PR. Does that sound reasonable for you? |

Can you hold off for a day? I think my pull will go in today and be more general. This test has been broken on 32-bit for a month now, don't think waiting another day will hurt. |

@finagolfin Okay, I understood |
