Jason Newcomb 8ded385ddc Improve needless_borrow lint.
* Lint when a borrow is auto dereferenced more than once
* Lint when the expression is used as the expression of a block for a match arm

Moves `needless_borrow` and `ref_binding_to_reference` to `dereference`
lint pass in preperation for `explicit_auto_deref` lint.
