It probably won't be unreachable for e.g. cargo check, but the previous code also used to set null to rmeta_x here, so it should be fine.

Ah, forgot we have cargo check 😆. Nice catch. Fixed
This was an overlook in 1891593 that forgot to replace other `rmeta_x`.

How to test and review this PR?
Two scenarios: One with
-Zsection-timings, and one without.If hovering on
semverorserde_spanned, the dep line will link to codegen start ofserde_core.On 1.91-beta or 1.92-nightly, the dep lines won't be drawn.
