Use DO_PRAGMA in libgomp.oacc-c-c++-common/reduction-1.c

2015-02-25  Tom de Vries  <tom@codesourcery.com>

	* testsuite/libgomp.oacc-c-c++-common/reduction-1.c (DO_PRAGMA)
	(check_reduction_op, check_reduction_macro, max, min):
	Declare.
	(test_reductions_int, test_reductions_minmax, test_reductions_bool): New
	function.
	(main): Use new functions.
