Seems the problem here is extremely long loc_chain lists (the longest one in
insert_into_intersection has 3740 entries), so e.g. insert_into_intersection is
extremely time consuming. Most of the locations in the long lists are of the
form
(plus:DI (value:DI ...) (const_int ...))
with different values and offsets.
