fortran, openmp: Add default: clause in order to avoid -Wmaybe-uninitialized warning

While the enum has only 4 enumerators and all of them are listed, in theory values
with the enum type could contain other values and so without default:
-Wmaybe-uninitialized warning for the s variable can happen.

	* dump-parse-tree.cc (show_omp_clauses): Add default: with
	gcc_unreachable () to avoid spurious -Wmaybe-uninitialized warnings.
