Description
There are some intrinsics that there should be no reason to call. For example core::intrinsics::size_of. This intrinsic is exposed by the safe function core::mem::size_of which should always be called instead.
I would like to suggest a Clippy lint that notices calls to no-reason-to-call intrinsics and recommends the right stable or safe wrapper to call instead.

- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reviewing the issue's examples of core::intrinsics::size_of and its core::mem::size_of wrapper, then determine which other intrinsics qualify as having stable or safe wrappers. Done means Clippy detects those calls and recommends the appropriate wrapper, with the supported intrinsic set and behavior defined.
