This is a general advice, and so shouldn't be repeated

This makes the labels redundant.

Add a new lint that detects the use of decimal literals as bit masks in
bitwise operations. Using decimal literals for bit masks can obscure the
intended bit pattern and reduce code readability. This lint encourages
the use of binary (`0b...`) or hexadecimal (`0x...`) notation to make
bit patterns explicit and easier to understand at a glance.

Example:

```rust
let masked = x & 14; // Bad: decimal literal as bit mask
let masked = x & 0b1110; // Good: bit pattern is explicit
```

Fixes rust-lang/rust-clippy#1775

Related to
https://rust-lang.github.io/rust-clippy/master/index.html#ptr_offset_with_cast
(and very much modelled off of its implementation).

This lint is motivated by cleaning up the output of
[c2rust](https://c2rust.com/), which contains many `.offset` calls with
by literal. The lint also nicely handles offsets by zero, which are
unnecessary.

I'm aware that the feature freeze is still in place, but this was
top-of-mind now. I'll patiently wait until the freeze is lifted.

The compiler will generate a special `main` function for the tests,
which caused this FP.

Now the program checks for transmutting from a struct containing a
single raw pointer to a reference.

```Rust
struct Foo(*const i32);
fn foo(foo: Foo) -> &i32 {
    unsafe { transmute(foo) }
}
```

bootstrap: add rustc-dev install target

I'm entirely new to bootstrap but there seemed to be no easy way to construct a sysroot with tools and librustc_driver.so. `./x install` is the command for that but as far as I can tell it doesn't include the rustc-dev files. This is my attempt at adding that.

`./x install rustc-dev` now does what you expect (at least on my machine™). If I'm understanding correctly this also means that `./x install` will now include rustc-dev files if `build.tools` contains `"rustc-dev"`.
