Rollup merge of #82297 - tmiasko:write-only, r=oli-obk
Consider auto derefs before warning about write only fields Changes from #81473 extended the dead code lint with an ability to detect fields that are written to but never read from. The implementation skips over fields on the left hand side of an assignment, without marking them as live. A field access might involve an automatic dereference and de-facto read the field. Conservatively mark expressions with deref adjustments as live to avoid generating false positive warnings. Closes #81626.
