59893bcab0 Fix temporary_cstring_as_ptr false negative
Fixes #4375.

Changes the check to test when `.unwrap().as_ptr()` is called on any
`Result<CString, _>` as suggested by @flip1995
(https://github.com/rust-lang/rust-clippy/issues/4375#issuecomment-520724123).

f71d59e6a6 Lint for type repetition in trait bounds.
This lint adds warning if types are redundantly repeated in trait bounds i.e. `T: Copy, T: Clone` instead of `T: Copy + Clone`. This is a late pass trait lint and has necessitated the addition of code to allow hashing of TyKinds without taking into account Span information.

HirIdify some lints

Unblocks https://github.com/rust-lang/rust/pull/58561 (a part of [rust-lang/rust#57578](https://github.com/rust-lang/rust/pull/57578)). Can we branch it like with https://github.com/rust-lang/rust-clippy/pull/3790? I can rebase on a different commit if need be.

Haven't had time to run tests yet, so I'd wait for Travis 🙈.

Fix ICE #3719+#3718 in lint match_ref_pats

Fixes #3719
This conveniently also fixes #3718

The ICE occurs when the match expression was a macro call, where the macro was defined in another file. Since we don't have the ability to reproduce this behavior with our UI tests (AFAIK), I couldn't add a test reproducing this ICE.. However, I added a test which is related to the ICE, to show the new behavior of the lint.

I tested it with the mscheme repo locally and the ICE didn't happen anymore.

2df14c3701 Add a lint to warn on T: Drop bounds
**What it does:** Checks for generics with `std::ops::Drop` as bounds.

**Why is this bad?** `Drop` bounds do not really accomplish anything.
A type may have compiler-generated drop glue without implementing the
`Drop` trait itself. The `Drop` trait also only has one method,
`Drop::drop`, and that function is by fiat not callable in user code.
So there is really no use case for using `Drop` in trait bounds.

**Known problems:** None.

**Example:**
```rust
fn foo<T: Drop>() {}
```

Fix `cast_sign_loss` false positive

This checks if the value is a non-negative constant before linting about
losing the sign.

Because the `constant` function doesn't handle const functions, we check if
the value is from a call to a `max_value` function directly. A utility method
called `get_def_path` was added to make checking for the function paths
easier.

c02367c4e9 Fix breakage due to rust-lang/rust#58079
The rustc change added HirId to a few nodes. As I understand it, the plan is
to remove the NodeId from these nodes eventually. Where the NodeId was
not being matched, I used `..` to try and avoid further breakage. Where it
was, I used `_` to make the fix easier when NodeId is removed.
