Never mind, I thought I had a case that showed different warning behavior but I was doing something wrong locally. Please ignore. |

Ah, it's too sensitive to ordering. Putting it in its own test file gives the warning I expected. |

This is like the existing test, but additionally shows a visible difference in the warning behavior. When the warning is produced for generic arguments rather than dataflow, it will show up even if we don't do dataflow for the local function whose callsite was removed. When branch removal breaks the link between the local function and its user method, this can result in warning suppressions that don't take effect. We could use the desired warning behavior to decide what the fix needs to do (whether it should do compiler-generated owning method detection before vs after constant propagation for the method).
