 score: Allow interrupts during thread dispatch

 Use a processor-specific interrupt frame during context switches in case
 the executing thread is longer executes on the processor and the heir
 thread is about to start execution.  During this period we must not use
 a thread stack for interrupt processing.

 Update #2809.
