Warn about explicit self-assignment
...
Warn about assignments where left-hand side place expression is the same
as right-hand side value expression. For example, warn about assignment in:
```rust
pub struct Event {
id: usize,
x: i32,
y: i32,
}
pub fn copy_position(a: &mut Event, b: &Event) {
a.x = b.x;
a.y = a.y;
}

Add the other overloadable operations to suspicious_arithmetic_impl
In #2268 I idly mused that the other user-overloadable operations could be added to this lint. Knowing that the lint was arguably incomplete was gnawing at the back of my mind, so I figured that I might as well make this PR, particularly given the change needed was so small.

Clippy pointer cast lint experiment
This PR is an experiment about exposing more parts of `rustc_typeck` for use in `clippy`. In particular, the code that checks where a cast is valid or not was exposed, which necessitated exposing [`FnCtxt`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_typeck/check/struct.FnCtxt.html ), and figuring out how to create an instance of that type inside `clippy`.
This was prompted by [this clippy issue](https://github.com/rust-lang/rust-clippy/issues/2064 ).
