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

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

oversight from https://github.com/rust-lang/rust/pull/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`
