Daniel Sanders b1aec70893 Fix non-determinism in Reassociate caused by address coincidences
Summary:
Between building the pair map and querying it there are a few places that
erase and create Values. It's rare but the address of these newly created
Values is occasionally the same as a just-erased Value that we already
have in the pair map. These coincidences should be accounted for to avoid
non-determinism.

Thanks to Roman Tereshin for the test case.
