/*Since IDT/Centaur didn't document cycle timings in the WinChip datasheets, and
I don't currently own a WinChip 2 to test against, most of the timing here is
a guess. This code makes the current (probably wrong) assumptions :
- FPU uses same timings as a Pentium, except for FXCH (which doesn't pair)
- 3DNow! instructions perfectly pair
- MMX follows mostly Pentium rules - one pipeline has shift/pack, one has
multiply, and other instructions can execute in either pipeline
- Instructions with prefixes can pair if both instructions are fully decoded
when the first instruction starts execution.*/
