Extend lang items to assert correct target. This commit extends the existing lang items functionality to assert that the `#[lang_item]` attribute is only found on the appropriate item for any given lang item. That is, language items representing traits must only ever have their corresponding attribute placed on a trait, for example. 2018-10-11 17:36:51 +00:00			`#![feature(lang_items)]`
