For now, we allow non-load-store, non-fence, non-csr instructions to trigger interrupts.
For MMIO instructions, they should not trigger interrupts since they may be sent to lower level before it writes back.
In order to support non-mmio load-store instructions to trigger interrupt, we allow load-store instruction trigger interrupt, while mmio-load-store instructions will flush pipe.
