[DAGCombiner] teach how to simplify xor/and/or nodes according to the following rules:
1) (AND (shuf (A, C, Mask), shuf (B, C, Mask)) -> shuf (AND (A, B), C, Mask)
2) (OR (shuf (A, C, Mask), shuf (B, C, Mask)) -> shuf (OR (A, B), C, Mask)
3) (XOR (shuf (A, C, Mask), shuf (B, C, Mask)) -> shuf (XOR (A, B), V_0, Mask)
4) (AND (shuf (C, A, Mask), shuf (C, B, Mask)) -> shuf (C, AND (A, B), Mask)
5) (OR (shuf (C, A, Mask), shuf (C, B, Mask)) -> shuf (C, OR (A, B), Mask)
6) (XOR (shuf (C, A, Mask), shuf (C, B, Mask)) -> shuf (V_0, XOR (A, B), Mask)
