c209fc9349 Fix string_lit_as_bytes lint for macros 
Prior to this change, string_lit_as_bytes would trigger for constructs
like `include_str!("filename").as_bytes()` and would recommend fixing it
by rewriting as `binclude_str!("filename")`.

This change updates the lint to act as an EarlyLintPass lint. It then
differentiates between string literals and macros that have bytes
yielding alternatives.

Closes #3205

3355: Lint to remove redundant `clone()`s r=oli-obk a=sinkuu

This PR adds lint `redundant_clone`. It suggests to remove redundant `clone()` that clones a owned value that will be dropped without any usage after that.

Real-world example: https://github.com/rust-lang/rust/compare/7b0735a..sinkuu:redundant_clone2

3331: Disable arithmetic lints in constant items r=oli-obk a=pengowen123

Currently this will not catch cases in associated constants. I'm not sure whether checking spans is the best way to solve this issue, but I don't think it will cause any problems.

3338: new_ret_no_self false positives r=flip1995 a=JoshMcguigan

~~WORK IN PROGRESS~~

I plan to fix all of the false positives in #3313 in this PR, but I wanted to open it now to start gathering feedback.

In this first commit, I've updated the lint to allow tuple return types as long as `Self` shows up at least once, in any position of the tuple. I believe this is the broadest possible interpretation of what should be allowed for tuple return types, but I would certainly be okay making the lint more strict. 

fixes #3313

9bd4e5469e Don't suggest cloned() for map Box deref 
Boxes are a bit magic in that they need to use `*` to get an owned value
out of the box. They implement `Deref` but that only returns a
reference. This means an easy way to convert an `Option<Box<T>>` to an
`<Option<T>` is:

```
box_option.map(|b| *b)
```

However, since b36bb0a6 the `map_clone` lint is detecting this as an
attempt to copy the box. Fix by excluding boxes completely from the
deref part of this lint.
