On x86-64 the sign extension is in C code, so it would be somewhat more
complicated to do a generic table or converter.

I think the tracer will always need to know if it's tracing 32bit
or 64bit though, because the interfaces are not always 100% compatible.
e.g. I suspect any serious one will need to look at memory
arguments for some cases and those generally differ.
