Merge #891

891: Remove hack to handle forward declared items r=philberty a=philberty

We used to use a compile_fns flag as a method to handle the case of code
such as:

```rust
fn foo() {
  bar()
}

fn bar() { }
```

The compile_fns flag when set to false would allow us to do a toplevel
scan to compile the initial fndecl prototype of the functions as a method
of handling the case of the call to bar() within the body of foo.

The backend is setup now that we can 'query_compile' by compiling the
item as required with a cache if we have already done so.
