@bors r-

These tests aren't in the right place, and they should have comments.

A comment in each test briefly saying these should fail and are currently unsound.

This isn't specialization. Maybe typeck?

Add a test for rust-lang#107975

The int is zero. But also not zero. This is so much fun.

This is a part of rust-lang#105107.

Initially I was going to just rebase rust-lang#108445, but quite a few things changed since then:
* The [mcve](rust-lang#105787 (comment)) used for rust-lang#105787 got fixed.[^upd2]
* You can't just `a ?= b` for rust-lang#107975 anymore. Now you have to `a-b ?= 0`. This is what this PR does. As an additional flex, it show that three ways of converting a pointer to its address have this issue:
  1. `as usize`
  2. `.expose_provenance()`
  3. `.addr()`
* rust-lang#108425 simply got fixed. Yay.

As an aside, the naming for `addr_of!` is quite unfortunate in context of provenance APIs. Because `addr_of!` gives you a pointer, but what provenance APIs refer to as "address" is the `usize` value. Oh well.

UPD1: GitHub is incapable of parsing rust-lang#107975 in the PR name, so let's add it here.

[^upd2]: UPD2: [The other mcve](rust-lang#105787 (comment)) does not work anymore either, saying "this behavior recently changed as a result of a bug fix; see rust-lang#56105 for details."
