        <pre>The AVX2 code produced for the following shufflevector

shufflevector <16 x i16> %9, <16 x i16> %8, <16 x i32> <i32 27, i32 26, i32 1,
i32 29, i32 26, i32 23, i32 11, i32 16, i32 1, i32 9, i32 16, i32 28, i32 13,
i32 4, i32 0, i32 24>

Does not shuffle correctly. It instead yields the following shuffle:

27, 26, 1, 29, 26, 29, 11, 27, 1, 9, 16, 23, 13, 4, 0, 19</pre>
