re PR middle-end/68221 (libgomp reduction-11/12 failures)
PR middle-end/68221
* 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.
* testsuite/libgomp.c++/reduction-12.C: Likewise.
