- `_Fill_memset` calls are qualified for consistency. - One `_Deallocate` call is qualified like a previous PR. - `_Make_shared_unbounded_array` and `_Allocate_shared_unbounded_array` overloads are consistently `_STD`-qualified, even though some don't need.

Notes:
_Fill_memsetis_STD-qualified for consistency, although it seems that_Fill_memsetis never used with "weird" types._Make_shared_unbounded_arrayand_Allocate_shared_unbounded_arrayoverloads are consistently_STD-qualified even though some don't need._Deallocatecall is_STD-qualified as drive-by since Properly destroyvector<shared_ptr<uninstantiable>>#4373 started to do this._Deallocatecall are all related tofunctionand will be handled in a future PR._STD addressof(meow)is used in some places instead of&. This seems necessary even if no ADL-incompatible type is involved, because an overloaded unaryoperator&can still do evil.adl_proof_allocatoris invented.
