PC alignment faults have priority over instruction aborts and we have code to deal with this in the translation front-ends. However during tb_lookup we can see a potentially faulting probe which doesn't get a MemOp set. If the page isn't available this results in EC_INSNABORT (0x20) instead of EC_PCALIGNMENT (0x22). As there is no easy way to set the appropriate MemOp in the instruction fetch probe path lets just detect it in arm_cpu_tlb_fill_align() ahead of the main alignment check. We also teach arm_deliver_fault to deliver the right syndrome for MMU_INST_FETCH alignment issues.
