After second thought
what if we have a large array of structs with a few uninitialized fields.
Initializing the rest will cost us anyway about the same.
Would it be better to check insize of
`emitStoresForZeroInit`/`emitStoresForPatternInit`, more precicely in
`emitStoresForConstant` before memset if IsAutoInit?
