Improve var-tracking dataflow iteration order
This builds upon the rev_post_order_and_mark_dfs_back_seme improvements
and makes vt_find_locations iterate over the dataflow problems for
each toplevel SCC separately, improving memory locality and avoiding
to process nodes after the SCC before the SCC itself stabilized.
On the asan_interceptors.cc testcase this for example reduces the
number of visited blocks from 3751 to 2867. For stage3-gcc
this reduces the number of visited blocks by ~4%.

* var-tracking.c (vt_find_locations): Use
rev_post_order_and_mark_dfs_back_seme and separately iterate
over toplevel SCCs.
