Fix a problem in alias analysis. It is about the misinterpretation of "Object".
This problem is exposed by r171325 which is already reverted. It is rather
hard to fabricate a testing case without it.
r171325 should *NOT* be resurrected as it has a potential problem although
this problem dosen't directly contribute to PR14988.
The bug is tracked by:
