Split out do_exception and do_iic_irq to handle bulk of the interrupt and exception processing. Parameterize the changes required to cpu state. The status.EH bit, which protects some data against double-faults, is only present with the MMU. Several exception cases did not check for status.EH being set, as required. The status.IH bit, which had been set by EXCP_IRQ, is exclusive to the external interrupt controller, which we do not yet implement. The internal interrupt controller, when the MMU is also present, sets the status.EH bit.
