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.

Committed this similar patch.

Thanks,
- Tom

	* 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.
