importing InstanceKind but not Instance is a bit weird 🤔

Do you need the resolve here? Can probably just do https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/context/struct.TyCtxt.html#method.intrinsic.is_some()?
(Since you never get to an intrinsic through a trait impl or whatever.)

Doh, I somehow completely missed that c-e already said this 🤦

…mpiler-errors,scottmcm Forbid tail calling intrinsics There is only one intrinsic that can be called on stable, as far as I can find, (`transmute`). And in general tail calling intrinsics doesn't make much sense. Alternative to rust-lang#144815 (and thus closes rust-lang#144815) Fixes rust-lang#144806 r? `@scottmcm`
