3087d1b0a2cbe8880ccbbb67744726ff4e5d390e Set bound/cmp/control for until wrap loop.
In patch r12-3136, niter->control, niter->bound and niter->cmp are
derived from number_of_iterations_lt. While for 'until wrap condition',
the calculation in number_of_iterations_lt is not align the requirements
on the define of them and requirements in determine_exit_conditions.
This patch calculate niter->control, niter->bound and niter->cmp in
number_of_iterations_until_wrap.
