Auto merge of #40597 - jseyfried:improve_span_expn_info, r=jseyfried
macros: improve `Span`'s expansion information This PR improves `Span`'s expansion information. More specifically: - It refactors AST node span construction to preserve expansion information. - Today, we only use the underlying tokens' `BytePos`s, throwing away the `ExpnId`s. - This improves the accuracy of AST nodes' expansion information, fixing #30506. - It refactors `span.expn_id: ExpnId` to `span.ctxt: SyntaxContext` and removes `ExpnId`. - This gives all tokens as much hygiene information as `Ident`s. - This is groundwork for procedural macros 2.0 `TokenStream` API. - This is also groundwork for declarative macros 2.0, which will need this hygiene information for some non-`Ident` tokens. - It simplifies processing of spans' expansion information throughout the compiler. - It fixes #40649. - It fixes #39450 and fixes part of #23480. r? @nrc
