Add function for printing a single OMP_CLAUSE
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.cc (print_omp_clause_to_str): Add new function.
* tree-pretty-print.h (print_omp_clause_to_str): Add declaration.
