The fur_list constructor for two ranges is leaving [1] in an undefined
state. The reason we haven't noticed is because after all the
shuffling in the last cycle there are no remaining users of it
(similarly for fur_list(unsigned, irange *)).
Since it's very late in the cycle, I would prefer to fix this, rather
than removing unused constructors altogether. Besides, we have uses
for them queued up for the next release.
Committed as obvious.
gcc/ChangeLog:
* gimple-range-fold.cc (fur_list::fur_list): Set m_local[1] correctly.
