[Bug debug/31412] [4.3] inf loop/long compile time, time spent in var-tracking.c

Well, vt_find_locations is quadratic in the number of edges and basic blocks
which
we have a _lot_ in this testcase.  Now, with the dataflow rewrite there may be
an easier way to compute the df problem.  Maybe Paolo has a suggestion here...
