Do not set both LOOP_C_INFINITE and LOOP_C_FINITE on vectorized loop
The setting is likely a typo and was meant to affect the scalar version
but even there LOOP_C_INFINITE is at most an optimization to the
niter analysis. Clearly setting it on the vectorized loop which we
just versioned to be _not_ infinite is bogus so the following change
removes this.

* tree-vect-loop-manip.c (vect_loop_versioning): Do not
set LOOP_C_INFINITE on the vectorized loop.
