  Commit 89f4f339130c ("For 'OMP_CLAUSE' in 'dump_generic_node', dump
the whole OMP clause chain") changed the dumping behavior for
OMP_CLAUSEs.  The old behavior is required for a follow-up
commit ("openacc: Add data optimization pass") that optimizes single
OMP_CLAUSEs.

gcc/ChangeLog:

        * tree-pretty-print.c (print_omp_clause_to_str): Add new function.
        * tree-pretty-print.h (print_omp_clause_to_str): Add declaration.
