proc_macro: Preserve spans of attributes on functions This commit updates the tokenization of items which are subsequently passed to `proc_macro` to ensure that span information is preserved on attributes as much as possible. Previously this area of the code suffered from #43081 where we haven't actually implemented converting an attribute to to a token tree yet, but a local fix was possible here. Closes #47941 2018-07-19 07:06:31 -07:00			`// aux-build:attribute-spans-preserved.rs`
