  "message": "Remove `tls::with_related_context`.\n\nThis function gets the current `ImplicitCtxt` and checks that its `tcx`\nmatches the passed-in `tcx`. It\u0027s an extra bit of sanity checking: when\nyou already have a `tcx`, and you need access to the non-`tcx` parts of\n`ImplicitCtxt`, check that your `tcx` matches the one in `ImplicitCtxt`.\n\nHowever, it\u0027s only used in two places: `start_query` and\n`current_query_job`. The non-checked alternatives (`with_context`,\n`with_context_opt`) are used in more places, including some where a\n`tcx` is available. And things would have to go catastrophically wrong\nfor the check to fail -- e.g. if we somehow end up with multiple\n`TyCtxt`s. In my opinion it\u0027s just an extra case to understand in\n`tls.rs` that adds little value.\n\nThis commit removes it. This avoids the need for `tcx` parameters in a\ncouple of places. The commit also adjusts how `start_query` sets up its\n`ImplicitCtxt` to more closely match how similar functions do it, i.e.\nwith `..icx.clone()` for the unchanged fields.\n",
