Ted Kremenek 9d0acca967 Updated CFGStmtVisitor and CFGRecStmtVisitor to have a notion of ...

"block-expressions" when visiting arbitrary expressions (via calls to
"Visit()").  This results in a refactoring where a dataflow analysis no
longer needs to always special case when handling block-expressions versus
non-block expressions.

Updated LiveVariables and UninitializedValues to conform to the slightly
altered interface of these visitor classes.

Thanks to Nuno Lopes for providing a test case that illustrated some
fundamental problems in the current design of the CFGXXXStmtVisitor classes
and how they were used.
