Remove value cache in SCEV comparator. (#100721)
The cache triggers almost never, and seems unlikely to help with
performance. However, when it does, it is likely to cause the comparator
to become inconsistent due to a bad interaction of the depth limit and
cache hits. This leads to crashes in debug builds. See the new unit test
for a reproducer.
