Other than the legacy `CoroElide`, the main purpose of this variable is to keep connection on the graph between the original copy and the `.resume`, `.destroy`, `.cleanup`, `.noalloc` splits. I would suggest just changing the name to read "f.splits" instead of `f.resumers`. It's a requirement for CGSCC call graph updating.
