score: Workaround for #2751
The ARM and PowerPC interrupt epilogues call _Thread_Dispatch() with
interrupts disabled (counter example: SPARC).
On SMP configurations, since inter-processor interrupts set the thread
dispatch necessary indicator this prevents a thread dispatch
notification in post-switch handlers (which all run with interrupts
disabled).
On all configurations, this is a serious issue for the interrupt
latency.
Update #2751
