Only enable magic fitted vectors in no-statistics builds.

Browse Source 
Source location zones pointer fixup is just too slow to be feasible.

Note: no-statistics builds of the graphical profiler don't perform fixup
of view-related pointers (e.g. zone info window zone pointer). This
won't cause crashes, because the pointers are still valid, but the
displayed data will be incorrect and potentially changing in time, as
the pointer can be reused for completely other zone.
