    kernel64 - Fix disabled interrupts during dbg/bpt trap
    
    * Interrupts were left improperly disabled during a dbg or bpt trap.
      i386 enables interrupts for these traps.  x86-64 needs to as well
      or it will hit an assertion in lwkt_switch() under certain circumstances.
    
    * Make debug code in lwkt_switch() also require INVARIANTS to function.
    
      NOTE: This is temporary debug code and should be removed at some point
      after 48-core testing is complete.
