If we DontCare a register write data, chisel will convert it to 0 (or somthing else?). Thus, for exceptionVec, we cannot simply DontCare the wdata. Instead, we have to assign them separately.

When sbuffer checks if it is empty, it needs to check if sq is also empty so there is no pending store. Errors will emerge rarely if we do not check sq.

Previously, we only give the first instrcution to backend when the packet causes a page fault. It will be stuck if not because waymask is 0 because no hit but hit includes ipf. So we seperates them.

We used to select writeback inst and update writebacked bit at the same cycle. However, it is too long to finish in one cycle. Now we select writeback inst and gen wbSelectedMask in cycle 1, then we use RegNext(wbSelectedMask) and writeback bit to select inst in the next cycle.
