Handle zero and empty cells (which also means zero) in OpenCL for division

Not sure if it makes sense to keep having OpDiv a subclass of Reduction. There
is no DIV() function that would take a range of cells, so it isn't really
comparable to the other Reducion subclasses. But let's keep that as it is for
now.

We need to handle three cases specially in the OpenCL: Dividing by an empty
cell which should produce an #DIV/0! error, dividing an empty cell by zero
which also should produce #DIV/0!, and dividing an empty cell with anything
else number which should produce 0.
