[nvptx] Add vector_length 128 testcases 

Add a couple of test-cases using vector length 128, while checking that we
override to vector length 32.

2019-01-03  Tom de Vries  <tdevries@suse.de>

	* testsuite/libgomp.oacc-c-c++-common/vector-length-128-1.c: New test.
	* testsuite/libgomp.oacc-c-c++-common/vector-length-128-3.c: New test.
