        PR debug/87039
        * omp-expand.c: Don't include debug.h.
        (adjust_context_and_scope): Add REGION argument.  Find DECL_CONTEXT
        from innermost outer parallel, task, teams or target that has a
        child_fn set, or, if there is no such outer region, use
        current_function_decl.  Do the DECL_CONTEXT adjustment regardless of
        whether a suitable BLOCK is found or not.
        (expand_parallel_call, expand_teams_call): Don't call
        adjust_context_and_scope here.
        (grid_expand_target_grid_body): Revert 2017-01-25 changes.
        (expand_omp_taskreg, expand_omp_target): Likewise.  Call
        adjust_context_and_scope.
        * dwarf2out.c (dwarf2out_early_global_decl): For
        decl_function_context recurse instead of calling dwarf2out_decl.

        * g++.dg/gomp/pr78363-4.C: New test.
        * g++.dg/gomp/pr78363-5.C: New test.
        * g++.dg/gomp/pr78363-6.C: New test.
        * g++.dg/gomp/pr78363-7.C: New test.
