[swift-dev] inefficient enum layout with optionals

i noticed that this enum takes up 9 bytes of storage 1> enum QuantizationTable 2. { 3. case q8 (UnsafeMutablePointer), 4. q16(UnsafeMutablePointer) 5. } 6> MemoryLayout.size $R0: Int = 9 but when i make it optional, it takes up 10 7> MemoryLayout.size $R1: Int = 10 ca
