126790999a new lint: Returning unit from closures expecting Ord 
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.

Fixes #5080

f760d77bdb Auto merge of #5597 - esamudera:slice_iter_next, r=flip1995 
New lint: iter_next_slice

Hello, this is a work-in-progress PR for issue: https://github.com/rust-lang/rust-clippy/issues/5572

I have implemented lint to replace `iter().next()` for `slice[index..]` and `array` with `get(index)` and `get(0)` respectively. However since I made a lot of changes, I would like to request some feedback before continuing so that I could fix mistakes.

Thank you!

Fixes #4226

This introduces the lint await_holding_lock. For async functions, we iterate
over all types in generator_interior_types and look for types named MutexGuard,
RwLockReadGuard, or RwLockWriteGuard. If we find one then we emit a lint.

Rollup merge of #5248 - ThibsG:ConstValues, r=flip1995 
Add lint on large non scalar const

This PR adds the new lint `non_scalar_const` that aims to warn against `const` declaration of large arrays. For performance, because of inlining, large arrays should be preferably declared as `static`.

Note: i made this one to warn on all const arrays, whether they are in a body function or not. I don't know if this is really necessary, i could just reduce this lint to variables out of function scope.

Fixes: #400
