FYI, it occurred to me that some corner cases might not be quite right 
with regards to alignment for the STRD instruction.  It seems that the 
hardware on which I tested it (Marvell Dove CPU) apparently copes with 
misaligned SDRD's when they're still 32-bit aligned.  So I need to run 
this code through a real validation harness on different hardware.
