Yeah, argp is eliminated to rsp + 16 instead of the correct rsp + 32 (there are
2 64-bit call used registers saved to stack in the prologue, callq pushes 8
bytes and rsp is adjusted by 8 to maintain the required stack alignment.
Vlad, can you please take a look?

Sure, I'll look at this. Simply I don't know when exactly (probably in a few
days) because I am working on many LRA PRs these days.
