Change ast::ty_param_bound so that all ty param bounds are represented as traits, with no special cases for Copy/Send/Owned/Const. typeck::collect generates the special cases. A consequence of this is that code using the #[no_core] attribute can't use the Copy kind/trait. Probably not a big deal? As a side effect, any user-defined traits that happen to be called Copy, etc. in the same module override the built-in Copy trait. Closes rust-lang#2284

let_and_return: avoid "does not live long enough" errors EDIT: Add rust-lang#3324 to the list of fixes <details> <summary>Description of old impl</summary> <br> Avoid suggesting turning the RHS expression of the last statement into the block tail expression if a temporary borrows from a local that would be destroyed before. This is my first incursion into MIR so there's probably room for improvement! </details> Avoid linting if the return type of some method or function called in the last statement has a lifetime parameter. changelog: Fix false positive in [`let_and_return`] Fixes rust-lang#3792 Fixes rust-lang#3324
