History
Kevin Lawton 54bc40971c Fixed repeated IO/string instruction acceleration bug. Not all the 
checks were honoring the EFLAGS.DF bit, but assuming it was always
equal to 0 (increment upward).  Plus some general cleanup of the
acceleration code.

I left the default of '--enable-repeat-speedups' to disabled, but
it seems pretty solid.  Definitely adds performance for disk
heavy workloads.
