	* omp-low.c (lower_rec_input_clauses): If C/C++ array reduction
	has non-zero bias, subtract it in integer type instead of
	pointer plus of negated bias.

	* testsuite/libgomp.c/reduction-11.c: Remove xfail.
	* testsuite/libgomp.c/reduction-12.c: Likewise.
	* testsuite/libgomp.c++/reduction-11.C: Likewise.
