Fixed bug in the transfer function for dereferences: the loaded value from EvalLoad should bind to the UnaryOperator*, not its subexpression.

When reporting branch conditions that evaluate to an uninitialized value,

highlight the most nested subexpression that appears most responsible (giving
the user better diagnostic feedback).
Updated test cases to illustrate this feature.

Changed merge operation for uninitialized values analysis to "intersect" (previous union).
...
The effect is that if a variable is uninitialized along a branch (but initialized along another), at merge points it is considered uninitialized. Previously we had the opposite behavior. The new behavior is more conservative, and more in line with gcc's behavior.

We accidentally were throttling the propagation of uninitialized state across
assignments (e.g. x = y). Thanks to Anders Carlsson for spotting this problem.

uninitialized values analysis.
