Thank you very much! That processor is built on the Excavator
architecture and lines up with the flag I put in the merge request (i.e.
it has the "fast LEA" hint).
I honestly didn't expect this much testing feedback, so thank you all!

P.S. I'm tempted to extend the test slightly to actually name the CPU
automatically.
