Static Item Duplication

This code:

``` rust
static TEST: int = 10;
static TEST2: &'static int = &TEST;
```

Produces the following IR:

``` llvm
@_ZN4TEST20h60213af30ae88ef1eaaE = internal constant i64 10
@const = private constant i64 10
@_ZN5TEST220hc4be0dea553bf116iaaE = internal constant i64* @const
```

So `TEST2` points to a duplicate of `TEST`, namely `@const`, rather than `TEST` itself.
