target-i386: Fix jmp im on x86_64 when executing 32-bit code
When running grub-install (32-bit) on an x86_64 Linux system in qemu, it
hangs on a pagefault forever, because an integer overflow occurs on the
IP on "jmp im". This patch masks overflows for 32 bit IPs on a 64 bit
system, just like it is done for 16 bit IPs already.
Using this patch, x86_64 openSUSE installation works again.
