Fix libgomp.oacc-c-c++-common/{loop-red-g-1,routine-g-1}.c for non-nvidia devices

2017-10-05  Tom de Vries  <tom@codesourcery.com>

	* testsuite/libgomp.oacc-c-c++-common/loop-red-g-1.c (main): Remove
	vector_length(32) clause from acc parallel directive.
	* testsuite/libgomp.oacc-c-c++-common/routine-g-1.c (main): Same.
