Fix for leak in thread vector allocation. 

In the vvp code generator, when zero/sign extending a sub-expression,
the sub-expression is first evaluated and stored in one location in
the thread vector store, then is copied and extended into a second
location. The storage used for the initial sub-expression evaluation
is never deallocated.
