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

[steven at gcc dot gnu dot org]

So this may be a non-monotonous dataflow problem...?

Do we have the dataflow equations of the var-tracking problem somewhere?  It'd
be interesting to check them against the actual implementation.
