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)
changelog: Expand [`integer_arithmetic`] to work with RHS literals and constants
fix the error-causing suggestion of 'borrowed_box'
Fixes#3128
Fix the suggestion of 'borrowed_box', which causes a syntax error because it misses necessary parentheses.

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
changelog: Add lint for comparing to empty slices
Fixes#6217

No lint in macro for `toplevel_ref_arg`

Remove redundant `expect_local()` call
The field `owner` of `HirId` is `LocalDefId` and `hir_id.owner.to_def_id().expect_local()` is redundant. I wonder they were introduced in some rustups.
