More valgrind integration. Vector objects keep displaced pointers
to vector data; they point to element 0 which is actually the third
element of the vector. If an object is only referenced by interior
pointers, Valgrind reports it as possibly leaked. This change
conditionally adds a pointer to the true start of the vector,
if Valgrind support is enabled.
