ca0be1bbedd6379d2645917bfff752486599b2a8 Remove unused legacy VRP code.
Removes unused legacy VRP code. The legacy mode in value_range's is
still around, as it can't be trivially deleted.
With this patch vr-values.cc melts away to simplify_using_ranges, but
I have avoided any renaming of actual files, since we have plans for
consolidation of other folding with ranges for the next release.
