ranges: commit range_lists_equiv() so that bool_implications compiles...
Grr. I need to commit this as well or the build breaks.
range_lists_equiv() takes two range lists and returns 1 if they are exactly
the same. It's used in bool_implications because we record all the states
when we return. Then we take all the states which are true when we return
1 and all that are true when we return 0. Then we look at how the states
which concern parameters. But if the range lists for a parameter are the
same for both 1 and 0 returns then it's not important and we don't
record that.
