middle-end/101291 - set loop copy of versioned loop
This fixes the vectorizer loop versioning code failing to clear
niter related info on the scalar loop as it assumed get_loop_copy
would work even for the outermost loop. The patch makes that
assumption hold by adjusting the loop versioning code.

* cfgloopmanip.c (loop_version): Set the loop copy of the
versioned loop to the new loop.
