Rollup merge of rust-lang#124715 - RalfJung:interpret-noreturn, r=compiler-errors interpret, miri: uniform treatments of intrinsics/functions with and without return block A long time ago we didn't have a `dest: &MPlaceTy<'tcx, Self::Provenance>` for diverging functions, and since `dest` is used so often we special-cased these non-returning intrinsics and functions so that we'd have `dest` available everywhere else. But this has changed a while ago, now only the return block `ret` is optional, and there's a convenient `return_to_block` function for dealing with the `None` case. So there no longer is any reason to treat diverging intrinsics/functions any different from those that do return.
