Note that trap #1 is compat_13_sigreturn, and give trap #3 to syscalls 

which require special handling, e.g. sigreturn on m68k.

This differs from the old sigreturn trap in that we require the syscall
number to be in register d0, just like the regular syscall entry point.
This will allow sigreturn to be versioned in the future without the need
to allocate another trap vector.
