Feature request: Lint on `drop_in_place` on types with no destructor

[theemathas]

If someone calls std::ptr::drop_in_place on a type that is statically known to have no destructor (e.g., c_void, &mut T, u8, etc), it would be nice if the compiler could give a warning.

Clippy has a drop_non_drop lint, which per documentation only flags calls to std::men::drop but could be extended (maybe there is already an issue for that, haven’t checked). Probably this can be uplifted to rustc if someone cares enough to put in the work.

rustc also has a dropping_copy_types lint.

rustc also has a dropping_copy_types lint.

We could easily extend both the dropping_copy_types and dropping_references lints.
