db9f3cbe30 Use the new special syscall entry point, and specify SYS___sigreturn14.
Makes the sigcode grow by 4 bytes.

Note that we are no longer able to use the HP-UX breakpoint "sigcodetrap"
hack here, as a result.  This means that BSD programs can no longer be
debugged by HP-UX debuggers.  *Sniff*  Don't break my heart...

35d282c8d5 Make sure SYS_exit and SYS___sigreturn14 are defined. Garbage collect
SYS_sigreturn.

38084c6615 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.

183f609c83 - Do not set TLCPUMASK on non-I/O nodes. That register exists only on
I/O nodes.  Previous code erroneously set it on CPU nodes only.
- In both the single- and multi-processor case, route all interrupts from
  I/O nodes to the primary CPU, for now.
