[gomp4] remove bogus tests

[Nathan Sidwell <nathan at acm dot org>]

I've committed this to gomp4 branch.  Both these tests are trying an 'acc loop' 
 outside of an offload region.  That's an error.

Of course, a diagnostic should be emitted, but the remainder of the tests are 
apparently checking valid constructs.  So I chose to  simply remove the 
erroneous case for the moment.

If anyone's wondering, a patch  I'm working on blew up on these two cases 
because it tried to manipulate the  loop and then discovered it wasn't in an 
offloaded function.
