Add support of FOR UPDATE in XC.
Also make sure the test case xc_for_update is not ignored in the regression test suite when the support gets added.
An attempt was done to add such a support but that was locking the entire table at the datanodes, where as only a subset of rows which are affected by the FOR UPDATE query should be locked.
