bors e7bdc5f9f8 Auto merge of #114330 - RalfJung:dagling-ptr-deref, r=oli-obk
don't UB on dangling ptr deref, instead check inbounds on projections

This implements https://github.com/rust-lang/reference/pull/1387 in Miri. See that PR for what the change is about.

Detecting dangling references in `let x = &...;` is now done by validity checking only, so some tests need to have validity checking enabled. There is no longer inherently a "nodangle" check in evaluating the expression `&*ptr` (aside from the aliasing model).

r? `@oli-obk`
