  Log:
  Add BASIC i386 binary support for the amd64 kernel.  This is largely
  stolen from the ia64/ia32 code (indeed there was a repocopy), but I've
  redone the MD parts and added and fixed a few essential syscalls.  It
  is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic)
  and p4.  The ia64 code has not implemented signal delivery, so I had
  to do that.
  
  Before you say it, yes, this does need to go in a common place.  But
  we're in a freeze at the moment and I didn't want to risk breaking ia64.
  I will sort this out after the freeze so that the common code is in a
  common place.
  
  On the AMD64 side, this required adding segment selector context switch
  support and some other support infrastructure.  The %fs/%gs etc code
  is hairy because loading %gs will clobber the kernel's current MSR_GSBASE
  setting.  The segment selectors are not used by the kernel, so they're only
  changed at context switch time or when changing modes.  This still needs
  to be optimized.
