The OpenACC update directive would cause an ICE if there was an error
parsing one of its clauses in the c front end. E.g. #pragma acc update
copy(a(1:10)). This patch fixes that. Also, it declare GOACC_update
inside libgomp_g.h
I've committed this patch to gomp-4_0-branch. A test case will be
provided later.
