restore functionality of OpenCL ParallelReductionVectorRef class

These functions were removed in 149a4d7566, although they quite clearly
do serve a purpose, and then e9586cf0b5 removed the no longer used
variables.
Without this, ParallelReductionVectorRef class simply does not work.
E.g. SUM(B1:B250) would not sum all the cells, but just one (testcase
is Test::testFormulaRefUpdateRange with OpenCL forced).
