When transferring to IRQ5 from an exception, save SYSCFG in memory across the transfer and clear the trace bit. When we get a single step exception, check whether we can safely clear the trace bit in SYSCFG. We can (and should) clear it after the first instruction of the interrupt handler; the first insn saves SYSCFG to the stack in all handlers.
