roland/x32-setjmp-mangle branch looks OK, except for that we
also need to make similar change in:

./sysdeps/unix/sysv/linux/x86_64/____longjmp_chk.S

If we want to be clever, we can reorder sysdeps/x86_64/setjmp.S to
use misaligned store for upper 32 bits of RBP instead of
shift and 32-bit store.  But I don't think it is really needed.

Thanks.
