Comment at: 
clang/unittests/Analysis/FlowSensitive/DataflowAnalysisContextTest.cpp:439
   Context.addFlowConditionConstraint(FC2, Y);
-  // JoinedFC = (FC1 || FC2) && Z = (X || Y) && Z
-  auto &JoinedFC = Context.joinFlowConditions(FC1, FC2);
+  // JoinedFC = ((!B && FC1) || (B && FC2)) && Z = ((!B && X) || (B && Y)) && Z
+  auto &B = Context.createAtomicBoolValue();
----------------
I'm a bit concerned by the need to update this (essentially) unrelated test. It 
implies the test is depending on implementation details that it shouldn't be 
concerned with.

Not for this patch, but if you have thoughts on how to simplify this test to do 
what it needs w/o being tied to the details of how joins work, that would be 
appreciated. At least, it seems worth a FIXME.

thanks

+        EXPECT_FALSE(Env.flowConditionImplies(FooVal));
+      });
----------------
should we also test the inverse?
```
EXPECT_FALSE(Env.flowConditionImplies(Env.makeNot(FooVal)));
```
That is, I would think we want to show that neither is provable.
