If both cpuarray and gpuarray are provided, the caller must ensure that
the provided arrays have identical values.
<P>
PETSc does NOT free the provided arrays when the vector is destroyed via
<A HREF="../Vec/VecDestroy.html#VecDestroy">VecDestroy</A>(). The user should not free the array until the vector is
destroyed.
