Fix openacc float reduction testcases
2017-10-04 Tom de Vries <tom@codesourcery.com>
* testsuite/libgomp.oacc-c-c++-common/par-loop-comb-reduction-3.c
(main): Reduce sum of arr elements. Assert that hres is exactly
representable in 32-bit floating point.
* testsuite/libgomp.oacc-c-c++-common/par-loop-comb-reduction-4.c
(main): Reduce sum of arr elements. Assert that hres and hmres are
exactly representable in 32-bit floating point.
* testsuite/libgomp.oacc-c-c++-common/reduction-7.c (gwv_np_4): Same.
