After the next patch, if a masked PIC interrupts causes CPU_INTERRUPT_POLL to be set, the CPU will spuriously get out of halted state. While this is technically valid, we should avoid that. Make CPU_INTERRUPT_POLL run apic_update_irq in the right thread and then look at CPU_INTERRUPT_HARD. If CPU_INTERRUPT_HARD does not get set, do not report the CPU as having work. Also move the handling of software-disabled APIC from apic_update_irq to apic_irq_pending, and always trigger CPU_INTERRUPT_POLL. This will be important once we will add a case that resets CPU_INTERRUPT_HARD from apic_update_irq. We want to run it even if we go through CPU_INTERRUPT_POLL, and even if the local APIC is software disabled.
