    Fix 'OMP_CLAUSE_TILE' operands handling in 'gcc/tree.c:walk_tree_1'
    
    In r245300 (commit 02889d23ee3b02854dff203dd87b9a25e30b61b4)
    "OpenACC tile clause support" that one had changed to three operands,
    similar to 'OMP_CLAUSE_COLLAPSE'.
    
    There is no (existing) test case where this seems to matter (likewise
    for 'OMP_CLAUSE_COLLAPSE'), but it's good to be consistent.
    
            gcc/
            * tree.c (walk_tree_1) <OMP_CLAUSE_TILE>: Handle three operands.
