make var-tracking iteration consistent
This eliminates the visited bitmap and makes whether a to be processed
block goes to the next or the current iteration only depend on its
position in RPO order rather than on whether it was visited in the
current iteration. As optimization single-BB iteration is processed
immediately.

* var-tracking.c (bb_heap_node_t): Remove unused typedef.
(vt_find_locations): Eliminate visited bitmap in favor of
RPO order check. Dump statistics about the number of
local BB dataflow computes.
