Replace set_last_error with set_last_error_and_return Took care of the simple patterns. Other patterns involved setting an error and then using `write_int` or setting metadata and returning -1. Unsure if those are in the scope of this change Looks like this has conflicts with #3779, so I can update when how to handle that is decided. Part of https://github.com/rust-lang/miri/issues/3930.
