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.

Fixed bug in transfer function for compound assignment operators when both operands where variables but had a non-pointer type (we fired an assertion).

Added more boilerplate transfer function support for pointer arithmetic.
Added more pretty-printing support for symbolic constraints.
Added transfer function support for handling enum values.
Minor pointer types cleanup in ExplodedGraphImpl.

IncompleteArrayType.  This should make code dealing with both incomplete 
and variable length arrays much more readable, plus it allows properly 
making the distinction between isVariableArrayType() and 
isVariablyModifiedType().  The patch is a little big, but it's 
strightforward. so I don't think there should be any issues.

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"

Remove DeclSpec::Invalid, a recently added bool that allowed the parser to detect if the decl spec was invalid.

For now, we will stick with the original strategy - clients of Parse::ParseDeclarationSpecifiers() should never have to know this.

A much better fix for http://llvm.org/bugs/show_bug.cgi?id=1987.
