Hi,

this patch makes the test-cases libgomp.oacc-c-c++-common/loop-g-{1,2}.c 
  work for non-nvidia devices.

For nvidia devices, a vector_length of 32 is required for the test to pass.

For devices with a non-32 forced vector_length, this test-case will fail 
the test for excess errors due to:
...
warning: using vector_length (x), ignoring 32
...

Fixed by removing the explicit vector_length setting. For nvidia 
devices, 32 is required, but that's also the forced default, so there's 
no need to be explicit about it.

Committed as obvious.

Thanks,
- Tom

2017-09-28  Tom de Vries  <tom@codesourcery.com>

	* testsuite/libgomp.oacc-c-c++-common/loop-g-1.c (main): Remove
	vector_length(32) clause from acc parallel directive.
	* testsuite/libgomp.oacc-c-c++-common/loop-g-2.c (main): Same.
