Auto merge of #93466 - cjgillot:query-dead, r=nagisa
Make dead code check a query. Dead code check is run for each invocation of the compiler, even if no modifications were involved. This PR makes dead code check a query keyed on the module. This allows to skip the check when a module has not changed. To perform this, a query `live_symbols_and_ignored_derived_traits` is introduced to encapsulate the global analysis of finding live symbols. The second query `check_mod_deathness` outputs diagnostics for each module based on this first query's results.
