This lint was downgraded to `pedantic` in part because rust-analyzer was not fully supporting it at the time per #10087. The support has been added over [a year ago](https://github.com/rust-lang/rust-analyzer/issues/11260), so seems like this should be back to style.
Another source of the initial frustration was fixed since then as well - this lint does not trigger by default in case only some arguments can be inlined.

Don't warn on proc macro generated code in `needless_return`
Fixes#13458Fixes#13457Fixes#13467Fixes#13479Fixes#13481Fixes#13526Fixes#13486
The fix is unfortunately a little more convoluted than just simply adding a `is_from_proc_macro`. That check *does* fix the issue, however it also introduces a bunch of false negatives in the tests, specifically when the returned expression is in a different syntax context, e.g. `return format!(..)`.
The proc macro check builds up a start and end pattern based on the HIR nodes and compares it to a snippet of the span, however that would currently fail for `return format!(..)` because we would have the patterns `("return", <something inside of the format macro>)`, which doesn't compare equal. So we now return an empty string pattern for when it's in a different syntax context.
"Hide whitespace" helps a bit for reviewing the proc macro detection change
