Subject: [PATCH] bug fix: The result of the pointer analysis is broken when it
 tries to do something for a flat literal node. Since the modeling of a flat
 literal node is only required for the additional runtime check which verifies
 the allocation site of objects pointed to(+ it has not yet fully
 implemented), no problem to turn it off. Turn back to the same way of the
 OOPSLA DOJ version.
