It hoists `destroy_value` instructions for non-lexical values. ``` %1 = some_ownedValue ... last_use(%1) ... // other instructions destroy_value %1 ``` -> ``` %1 = some_ownedValue ... last_use(%1) destroy_value %1 // <- moved after the last use ... // other instructions ``` In contrast to non-mandatory optimization passes, this is the only pass which hoists destroys over deinit-barriers. This ensures consistent behavior in -Onone and optimized builds.
