Unrolled build for rust-lang#121084

Rollup merge of rust-lang#121084 - oli-obk:create_def_forever_red2, r=WaffleLapkin

Make sure `tcx.create_def` also depends on the forever red node, instead of just `tcx.at(span).create_def`

oversight from rust-lang#119136

Not actually an issue, because all uses of `tcx.create_def` were in the resolver, which is `eval_always`, but still good to harden against future uses of `create_def`
