[issue9155] Reserve COMPARE_OP for rich comparisons

[Demur Rumed]

Demur Rumed <junkmute at hotmail.com> added the comment:

I've attached the original patch without whitespace, and am also including modifications to this portion of the interpreter which remove ROT_FOUR, DUP_TOPX while adding ROT_THREE_TWO, DUP_TOP_TWO, DUP_ROT_THREE. I've seen a 5% speed increase with timeit.Timer("a[0]+=0","a=[0]")

Also modified the optimizer to reject code with a size over 32767 instead of 32760. That's most likely a useless modification which may be preferred ignored
