To me, knowing that CMOV is supported, and the fact that it's fast,
are two different things.

I can't think of an example right now to show when it could be
profitable to use cmov even though it's slow, but if I understood
correctly your change, P4 user will now use suboptimal CABAC code
because they use an ASM code that depends on having a fast
implementation of CMOV.

Other than simplifying configure script, were there a reason to make
the change your did?

If not, I think this needs to be reverted, though I'd prefer to hear
what Michael may have to say about this.
