This fixes #732 - well, partly, it doesn't adress Hash impls, but the use of mutable types as map keys or set members

changelog: add mutable_key_type lint

Sorry was absent for the past few days. Can you add tests for this lint. I don't really get, why every function/method signature gets checked, but only map/set types get linted.

IIUC only the check_local function can ever trigger the lint, except a function has a HashMap<InteriorMut, _> as an argument. Maybe it gets more clear with tests.

Fixed the lint and added a test. The lint will check for arguments, return types and non-wildcard locals.

☔ The latest upstream changes (presumably #4930) made this pull request unmergeable. Please resolve the merge conflicts.

Am I missing something or would it be easier to just use the check_ty function of LateLintPass with hir_ty_to_ty instead of walking the signature of functions?

Probably. I took this route to ensure I know what places we lint.

That's a good argument for this way of writing the lint.
