c2cf40cdcd Auto merge of #6284 - camsteffen:rustc-sym, r=flip1995 
Use const sym where possible

I ran a regex search and replace to use const `sym` values where possible. This should give some performance boost by avoiding string interning at runtime.

Con: It is not as consistent as always using `sym!`.

I also changed an internal lint to suggest using `sym::{}`, making an assumption that this will always work for diagnostic items.

a2bf404d34 Auto merge of #6101 - pitiK3U:from_iter_instead_of_collect, r=flip1995 
Add lint: from_iter_instead_of_collect

Fixes #5679

This implements lint for `::from_iter()` from #5679 not the general issue (`std::ops::Add::add`, etc.).
This lint checks if expression is function call with `from_iter` name and if it's implementation of the `std::iter::FromIterator` trait.

Improve suggestions for several lints

This PR is a follow-up of this [Zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/filter_next.20lint).

It unifies placeholders for `methods` module and improves several suggestions for `filter_next`, `filter_map_next` and `map_unwrap_or` lints.
