Rollup merge of #108047 - oli-obk:machine->🞋, r=RalfJung

Browse source 
Use `target` instead of `machine` for mir interpreter integer handling.

The naming of `machine` only makes sense from a mir interpreter internals perspective, but outside users talk about the `target` platform. As per https://github.com/rust-lang/rust/pull/108029#issuecomment-1429791015
