GRExprEngine now records stores to "uninitialized lvalues" (which are sinks in
the ExplodedGraph).

We will implement symbol "unification" later.

but the fixes are reasonable.

Fixed bug in transfer functions for sizeof(*); we were incorrectly evaluating to
a value of the wrong type.

Fixed bug in transfer functions for compound assignments where we did not properly
handle assignments involving dereferences of symbolic values.

--grsimple except that it visualizes the ExplodedGraph using dot and
outputs the current function being analyzed.  --grsimple is now silent
except when it emits diagnostics.

Moved driver logic for --grsimple to GRSimpleVals.cpp.

these operations) into GRTransferFuncs and its subclasses.  Originally all
of this logic was handled by the class RValue, but in reality different
analyses will want more flexibility on how they evaluate different values.

Transfer functions migrated so far: "Cast"
