[PATCH] Patch for missing debug info of type being explicitly casted to

[David Blaikie]

Looks good to me. Though one day we might want to generalize the name of this function and call it from a few more places where types can be referenced without otherwise being attached to debug info ( "func(void*); ... func(new T());" comes to mind - for some trivial type T (ie: no ctor, etc)).
