Fixes issue: #251

Hey @gnurizen 👋 The commit I authored in DataDog@630fd97 unfortunately doesn't fully fix #251.

I think we should consider the alternative described in:

b. Add more logic in disassembly code: Add logic in decode_amd64.c to take into account variables in temporary registers, and the case where %rdi is populated via mov then add. We could potentially fix both issues at the cost of additionally complexity.

So we better cover all the edge cases discussed in that issue (didn't get around to implementing this yet though).

Additionally, as far as I can tell, the packaged python in ubuntu is compiled with --enable-optimizations, --with-lto, so this shouldn't impact stock python 3.12 on ubuntu x86-64. Do you have more information on how you reproduced this? We might have missed something on the original issue.
