This issue arose because we were not considering punpckldq as
one of the 3-operand AVX instructions (which require us to duplicate
the source register when encoding an SSE 2-operand form).
This bug showed up in managed C++, so the test is in IL.
The test is failing in RyuJIT/x86, so issue dotnet/coreclr#6940 has been opened,
and it is disabled for x86.
