resolve: Remove remaining special cases from built-in macros
Edition and definition sites of the macros are now also taken from the `#[rustc_builtin_macro]` definitions in `libcore`.
---
The edition switch may be a breaking change for `Rustc{Encodable,Decodable}` derives if they are used in combination with the unstable crate `serialize` from sysroot like this
```rust
extern crate serialize;
use serialize as rustc_serialize;
#[derive(RustcEncodable)]
struct S;
```
(see the updated `ui-fulldeps` tests).
