Auto merge of #126844 - scottmcm:more-ptr-cast-gvn, r=saethlin
Remove more `PtrToPtr` casts in GVN This addresses two things I noticed in MIR: 1. `NonNull::<T>::eq` does `(a as *mut T) == (b as *mut T)`, but it could just compare the `*const T`s, so this removes `PtrToPtr` casts that are on both sides of a pointer comparison, so long as they're not fat-to-thin casts. 2. `NonNull::<T>::addr` does `transmute::<_, usize>(p as *const ())`, but so long as `T: Thin` that cast doesn't do anything, and thus we can directly transmute the `*const T` instead. r? mir-opt
