Rollup merge of #140576 - m-ou-se:fragile-tests, r=compiler-errors

Remove fragile equal-pointers-unequal tests.

Same as https://github.com/rust-lang/rust/pull/139176

---

These tests were added in #127003

These tests stop working when I change implementation details of format_args!(). These tests shouldn't rely on such implementation details.

Do these tests test anything that isn't already covered by other tests? If so, they should be expressed in a less fragile way that doesn't rely on internal details of format_args!().

cc `@GrigorenkoPV,` author of these tests.
