Rust puts garbage in data structures containing static lists

[mstewartgallus]

The following gist compiles incorrectly, and prints garbage instead of the correct value.

I think I came across this when doing my work with consts; iirc, looking at the LLVM IR that this produces shows various weird pointer casts that end up passing the complete wrong value when printing the list.

Slightly better test case:

use std::io;

struct T (&'static [int]);
static t : T = T (&'static [5, 4, 3]);
fn main () {
    assert_eq!(t[0], 5);
}

Reproduced with 93c270c. Nominating for milestone 5, production-ready

I believe that this may be the cause of #7617
