borrow_as_ptr does not detect implicit casts due to coercions

[RalfJung]

Summary

borrow_as_ptr should detect &expr in places where that is coerced to a raw pointer, and suggest &raw const expr instead (and similar for the mutable case)

Lint Name

borrow_as_ptr

Reproducer

I tried this code:

#![deny(clippy::borrow_as_ptr)]

fn main() {
    let val = 1;
    let p: *const i32 = &val;
}

I expected to see this happen:
the lint should fire

Instead, this happened:
it does not fire
