<pre>The following EVEX instruction is decoded with an XMM register used incorrectly
in address calculation. This happens for quite a few similar EVEX instructions.
I tried assembling the LLVM Output using gas and received an error.
Bytes: 62 a1 2d d4 db 6c b6 08
LLVM Output: vpandd 32(%rsi,%xmm14,4){1to16}, %zmm26, %zmm21 {%k4} {z}
Error from gas: unsupported vector index register for `vpandd'
Expected: vpandd 32(%rsi, %r14, 4){1to16}, %zmm26, %zmm21{%k4}{z}</pre>
