v1_2 = {i_1(D), i_1(D), i_1(D), i_1(D)};
_6 = i_1(D);
_7 = i_1(D) * 3;
_8 = i_1(D);
_9 = i_1(D) * 3;
_10 = i_1(D);
_11 = i_1(D) * 3;
_12 = i_1(D);
_13 = i_1(D) * 3;
_3 = {_7, _9, _11, _13};
err, why would DOM which runs after lower_vector_ssa _not_ CSE those
multiplications? Pleas attach dom2-details dumps.
