One potential solution is to let the resolver ISA level becomes the highest one
in target_clones instead of the default one.
Then it will not get the memory/register mismatch when passing/returning
argument

I would rather do not touch all the ISA level since it might cause unexpected
problems after thinking twice.
Since there is also indirect call, I will throw an error for this case.

Hmm, it is interesting that I even could not reproduce that on the same
machine.

Maybe I could first start with a bisect since GCC12.1 is known to ok and
GCC13.1 is known to fail.
