Confirmed. We have a loop with a couple thousands of bbs and >20k datarefs,
and we die in a quadratic loops in compute_all_dependences. Can be easily
fixed with a PARAM limiting the data ref analysis.
While doing this, I noticed that there is no reason for
find_data_references_in_loop to be extern and made it static. Also predcom and
parloops are not ready for compute_data_dependences_for_loop returning false,
so I fixed this as well.
