OpenMP: Fix for ICE in tree-nested.cc.

Use gimple_omp_target_clauses() instead of gimple_omp_taskreg_clauses()
when stmt is GIMPLE_OMP_TARGET, to avoid an as_a<> ICE.  The code
immediately following this is already conditionalized in the same way.

gcc/ChangeLog
	* tree-nested.cc (convert_tramp_reference_stmt): Use the correct
	accessor for GIMPLE_OMP_TARGET clauses.
