In ScalarEvolution::forgetValue, eliminate any SCEVUnknown
entries associated with the value being erased in the
folding set map. These entries used to be harmless, because
a SCEVUnknown doesn't store any information about its Value*,
so having a new Value allocated at the old Value's address
wasn't a problem. But now that ScalarEvolution is storing more
information about values, this is no longer safe.
