rustc_span: Optimize syntax context comparisons Including comparisons with root context. - `eq_ctxt` doesn't require retrieving full `SpanData`, or taking the span interner lock twice. - Checking `SyntaxContext` for "rootness" is cheaper than extracting a full outer `ExpnData` for it and checking *it* for rootness. The internal lint for `eq_ctxt` is also tweaked to detect `a.ctxt() != b.ctxt()` in addition to `a.ctxt() == b.ctxt()`. |
