I updated the "blea" test in the merge request so it now displays the
processor brand name on x86_64; however, it is not fetched under i386
because CPUID was not introduced until later 486 processors. I've
attached it to this e-mail if anyone wants to take a look to ensure I
haven't broken
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

Thank you for the report.
According to Agner Fog's table, complex LEA instructions should have a
3-cycle latency on that architecture (Haswell). Optimisations with this
instruction are proving interesting because there's such a variety
between processor architectures. There are some that are
