Don't warn on proc macro generated code in `needless_return` Fixes rust-lang#13458 Fixes rust-lang#13457 Fixes rust-lang#13467 Fixes rust-lang#13479 Fixes rust-lang#13481 Fixes rust-lang#13526 Fixes rust-lang#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 changelog: none

…atthiaskrgr Clippy: Backport `needless_return` fix r? `@Manishearth` This cherry-picks rust-lang/rust-clippy#13464, so that it gets into master and with that into `beta` tomorrow, so that the bug in this lint doesn't hit `beta`. Changes look quite big, but most of them are whitespace changes because of the introduction of an `_inner` function. In reality it only adds 2 checks.
