Yes, the problem is that eax, edx and ecx are live there (might be arguments)
and ebx is reserved for PIC pointer, so at that spot is no QImode register
available. I guess either my builtins.c change could be conditionalized on
if it is really needed, or on i386 it would need to avoid a QImode store and
use
SImode instead. Looking into it.
