[StructLayout(LayoutKind.Sequential, Size = 16)]
public unsafe struct Data
{
    public fixed byte bytes[16];
}

Running the swift lowering algorithm on the following struct results in incorrect lowering. I did debug on mono and the resulting lowering is a single unsigned byte. I would expect this to be lowered into two int64.

@jkoritzinsky should such constructs be supported by the swift struct lowering algorithm?
