Account prefetch_mod and unroll_factor for the computation of the prefetch count.
2010-06-14 Changpeng Fang <changpeng.fang@amd.com>
* tree-ssa-loop-prefetch.c (nothing_to_prefetch_p): New. Return
true if no prefetch is going to be generated for a given group.
(estimate_prefetch_count): Use prefetch_mod and unroll_factor to
estimate the prefetch_count.
(loop_prefetch_arrays): Call nothing_to_prefetch_p; estimate the
prefetch count by considering the unroll_factor and prefetch_mod
for is_loop_prefetching_profitable.
