ENH: missingdata: Create count_reduce_items function
This function either cheaply returns the product of the sizes of
all the reduction axes, or counts the number of items which will
be used in a reduction operation when skipna is True. Its purpose
is to make it easy to do functions like np.mean and np.std.
