Adjust inner loop cost scaling
This makes use of the estimated number of iterations of the inner loop
to limit --param vect-inner-loop-cost-factor scaling. It also reduces
the maximum value of vect-inner-loop-cost-factor to 10000 making it
less likely to cause overflow of costs.

* doc/invoke.texi (vect-inner-loop-cost-factor): Adjust.
* params.opt (--param vect-inner-loop-cost-factor): Adjust
maximum value.
* tree-vect-loop.c (vect_analyze_loop_form): Initialize
inner_loop_cost_factor to the minimum of the estimated number
of iterations of the inner loop and vect-inner-loop-cost-factor.
