Patch 1:
    Made the changes discussed in the previous thread: now using inc/dec,
    removed the compare, and using one register less on x86_64.

Patch 2:
    No change.

Patch 3:
    No change.

Patch 4:
    No change.

Patch 5:
    No change.

Patch 6:
    Incorporated the changes made to patch 1 and corrected the number of xmm
    registers used.  Also added the changes discussed last time to the MIN/MAX
    macros to allow 3-operand instructions.

Patch 7:
    No change.

Does anyone have any final comments?  Spelling?  Grammar?  Layout?  Cosmetics?
Gross objections?  Otherwise I consider these to be finished and ready to be
