Tom,
as we discussed this patch removes the GOACC_kernels call, which forwards to
GOACC_parallel. We simply call GOACC_parallel directly.
ok for gomp4 branch?

gcc/
* omp-low.c (expand_omp_target): Convert to
BUILT_IN_GOACC_PARALLEL. Remove BUILT_IN_GOACC_KERNELS cases.
* omp-builtins.def (BUILT_IN_GOACC_KERNELS): Delete.
libgomp/
* oacc-parallel.c (GOACC_kernels): Delete.
