Update the existing arithmetic lint

re: #6209

Updates the lint to not the error message if RHS of binary operation `/` of `%` is a literal/constant that is not `0` or `-1`, as suggested [here](https://github.com/rust-lang/rust-clippy/issues/6209#issuecomment-715624354)

e1a2845558 Auto merge of #6226 - Urcra:master, r=flip1995 
Add lint for comparing to empty slices instead of using .is_empty()

Hey first time making a clippy lint

I added the implementation of the lint the `len_zero` since it shared a lot of the code, I would otherwise have to rewrite. Just tell me if the lint should use it's own file instead

Lint items after statements in local macro expansions

The items_after_statements lint was skipping all expansions.  Instead
we should still lint local macros.

Fixes #578

No lint in macro for `toplevel_ref_arg`

Do not lint when the span is from a macro.

New internal lint: Invalid paths

Add a new internal lint that detects invalid paths in the `util::paths` and fix some invalid paths found.

This commit partially addresses #6047 but the lint would have to be run before running tests to close that issue.
