Rollup merge of #22700 - nick29581:ints_hash, r=alexcrichton

 fmt and hash are pretty straightforward I think. sync is a bit more complex. I thought one or two of the `isize`s ought to be `i32`s, but that would require a bunch of casting (the root cause being the lack of atomics other than isize/usize).
