omp-oacc-kernels-decompose.cc: fix -fcompare-debug with GIMPLE_DEBUG
GIMPLE_DEBUG were put in a parallel region of its own, which is not
only pointless but also breaks -fcompare-debug. With this commit,
they are handled like simple assignments: those placed are places
into the same body as the loop such that only one parallel region
remains as without debugging. This fixes the existing testcase
libgomp.oacc-c-c++-common/kernels-loop-g.c.
Note: GIMPLE_DEBUG are only accepted with -fcompare-debug; if they
appear otherwise, decompose_kernels_region_body rejects them with
a sorry (unchanged).

* omp-oacc-kernels-decompose.cc (top_level_omp_for_in_stmt,
decompose_kernels_region_body): Handle GIMPLE_DEBUG like
simple assignment.
