<div>
<pre>The below are two examples of decodings produced by LLVM where the instruction
is suffixed with 'l', but accesses a 16-bit register.
Bytes: 66 d1 d2
Output: rcll %dx
Bytes: 66 b8 09 35
Output: movl $13577, %sp
I suspect this is a result of ignoring the 0x66 prefix when choosing opcode
suffix.</pre>
