Some AST nodes which stands for implicit initialization is shared. The analyzer will do the same evaluation on the same nodes resulting in the same state. The analyzer will "cache out", i.e. it thinks that it visited an already existing node in the exploded graph. This is not true in this case and we lose coverage. Since these nodes do not really require any processing from the analyzer we just omit them from the CFG. Differential Revision: https://reviews.llvm.org/D71371
