perf evlist: Introduce backward_mmap array for evlist
Add backward_mmap to evlist, free it together with normal mmap.
Improve perf_evlist__pick_pc(), search backward_mmap if evlist->mmap is
not available.
This patch doesn't alloc this array. It will be allocated conditionally
in the following commits.
