Panic during linting involving complicated match statements

[Ameobea]

I've encountered an error when linting my project resulting in a panic while compiling.

• Compiler Version: rustc 1.19.0-nightly (5f39668 2017-05-25)
• Failing Code:

match Some(()) {
    Some(_) => unsafe { ptr::write(ptr::null_mut() as *mut u32, mem::transmute::<[u8; 4], _>([0, 0, 0, 255])) },
    None => unsafe { ptr::write(ptr::null_mut() as *mut u32, mem::transmute::<[u8; 4], _>([13, 246, 24, 255])) },
}

• Backtrace: https://gist.github.com/Ameobea/d57a03bf41993522bddf16afd8b69017

I've created a PR that includes a new test that causes a panic. I was unable to determine the cause of the panic myself or go about fixing it, however.

It's the copy paste Lint's fault. We probably messed up something around body tables again
