Summary:
VECTOR_SHUFFLE concatenates the vectors in an vectorwise fashion.
<0b00, 0b01> + <0b10, 0b11> -> <0b00, 0b01, 0b10, 0b11>
VSHF concatenates the vectors in a bitwise fashion:
<0b00, 0b01> + <0b10, 0b11> ->
0b0100 + 0b1110 -> 0b01001110
<0b10, 0b11, 0b00, 0b01>
We must therefore swap the operands to get the correct result.
The test case that discovered the issue was MultiSource/Benchmarks/nbench.
