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.

3346: Add lint for calling `mem::discriminant` on a non-enum type r=flip1995 a=HMPerson1
Also, if the type is a reference to an enum, we suggest removing `&`s and/or dereferencing.

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.

3339: Check for known array length in `needless_range_loop` r=phansch a=HMPerson1
In `VarVisitor`, we now keep track of the type of the thing that was directly indexed and, if it's an array, check if the range's end is (or is past) the array's length.
Fixes #3033
