[vtk-developers] Addition flag for valgrind

[Bill Lorensen]

Foks,

I suggest we add the flag:
--track-origins=yes
to valgrind.
"Controls whether Memcheck tracks the origin of uninitialised values. By
default, it does not, which means that although it can tell you that an
uninitialised value is being used in a dangerous way, it cannot tell you
where the uninitialised value came from. This often makes it difficult to
track down the root problem. "
http://valgrind.org/docs/manual/mc-manual.html

For example, it helped me find this error:
http://review.source.kitware.com/#/t/2301/

which would have been hard to find without it.
