In the current type conversion, MemRef types are lowered to emitc.array types, While using alloc operation - the lowered result becomes a ptr<element-type>. This creates a mismatch because load and store operations expect an emitc.array type. As a result, builtin.unrealized_conversion_cast ops are inserted automatically to bridge between the pointer type and the array type.
