dc0609c247 feature-gate lint reasons 
We take stability seriously, so we shy away from making even seemingly
"trivial" features insta-stable.

d570b36cd9 Auto merge of #54778 - scottmcm:stabilize-ihle, r=pnkfelix 
Stabilize impl_header_lifetime_elision in 2015

~~This is currently blocked on https://github.com/rust-lang/rust/issues/54902; it should be good after that~~

It's already stable in 2018; this finishes the stabilization.

FCP completed (https://github.com/rust-lang/rust/issues/15872#issuecomment-417953153), proposal (https://github.com/rust-lang/rust/issues/15872#issuecomment-412759783).

ca2639e82e Auto merge of #55014 - ljedrz:lazyboye_unwraps, r=matthewjasper 
Prefer unwrap_or_else to unwrap_or in case of function calls/allocations

The contents of `unwrap_or` are evaluated eagerly, so it's not a good pick in case of function calls and allocations. This PR also changes a few `unwrap_or`s with `unwrap_or_default`.

An added bonus is that in some cases this change also reveals if the object it's called on is an `Option` or a `Result` (based on whether the closure takes an argument).

Rollup merge of #55025 - ehuss:missing-lifetime-err-msg, r=petrochenkov 
Add missing lifetime fragment specifier to error message.

A very minor issue, `lifetime` was missing from the error list.
I left `literal` in the list, even though it is unstable. It looks like it may stabilize soon anyways.

Fix #54707 - parse_trait_item_ now handles interpolated blocks as function body decls

Previously parsing trait items only handled opening brace token and semicolon, I added a branch to the match statement that will also handle interpolated blocks.
