[Omp] data scope clause

[Meadows, Lawrence F]

In C, all arguments are passed by value, thus are always
private. So the dummy arguments corresponding to the
actual arguments x,y,z will be private inside of k_routine,
regardless of how they are declared externally -- exactly
as if they had been declared as local variables inside
of k_routine. Their initial value will be whatever was
passed to k_routine.

Pointers are a different matter -- the pointer might
be private while the pointed-to might not be.
