Lint wrong integer range comparisons

[Boddlnagg]

I don't know if an issue already exists for something like this, but at least I couldn't find one:
I suggest to add a lint that checks for conditions such as

• i > A || i < B where A and B are integer literals (or constants?) with A ≤ B (always true)
• i < A && i > B where A and B are integer literals (or constants?) with A ≤ B (always false)

After rust-lang/rust#32311 is stabilized, clippy could also suggest to use Range::contains.
