    alignment: set alignment on structs
    
    This uses an alternate idea for setting the structure alignments. Lets
    see if this silents the ARM builder cast alignment issues.
    
    GSlice (which is what is used for GObjects) guarantees a 2-pointer size
    allocation, which means we can be ensured that the alignment is at least
    8 bytes.
