I addressed all comments except this one :D,
To use `llvm::StoreOp` we need to construct `mlir::DenseElementsAttr`, and it
takes `Array<Attribute>`, but we have `Array<Value>` for Constant values. it's
easy to get the attribute from them using getDefiningOp but now what is needed
is to get value from non constant value for example x in `{ 1, 2, X, 3}`
