I was more or less correct on this one.  Apparently this was not even
defined by us but by one of our very large chip vendors who shall remain
nameless.  Rather than the nicer solution of just defining an array of 64
bit regs, they did this which necessitates some nastiness when dealing with
different endians.  The alignment field ensures that the overall structure
is 64 bit aligned which is a handy thing to be on mips.

I was correct.  This is future proofing and currently unnecessary.  I'll
remove it.

cheers,
