bors d7c59370ce 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.

The goal of this directory is to track the quality of MIR that is given to codegen in a standard -O condiguration.

As such, feel free to --bless whatever changes you get here, so long as doing so doesn't add substantially more MIR.
