auto merge of #14250 : alexcrichton/rust/gc, r=brson

This commit removes `@T` from the compiler by moving the AST to using `Gc<T>`. This also starts treating `Gc<T>` as `@T` in the same way that `Box<T>` is the same as `~T` in the compiler.

After this hits a snapshot, the `@T` syntax should be able to be removed completely.
