Compiling a file for testing without any tests crashes LLVM

[jschaf]

Compiling an empty file with rustc empty.rs --test fails. I'm using rust-nightly on windows 8.

fn main(){}

$ rustc src/empty.rs  --test
src\empty.rs:3:1: 3:12 warning: code is never used: `main`, #[warn(dead_code)] on by default
src\empty.rs:3 fn main(){}
               ^~~~~~~~~~~
Assertion failed!

Expression: Section->Number != -1 && "Sections with relocations must be real!"

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Closing as a dupe of #13793, but thanks for the report!
