...
hazard was not a straight forward merge. I changed the way the LSU and IFU generate IFUStallF and LSUStallM. They need to be suppressed by TrapM now.

Removed TrapM from the LSU and IFU. TrapM is replaced with FlushW for both. (Don't like this for the IFU).
...
FlushW prevents writting the cache, dtim, and bus state. FlushW still gates HTRANS.
FlushW does not impact the mealy outputs of the cache and bus FSMs and hazard is updated to
not stall W if we get a trap.

Changed FDivBusyE to stall the whole pipeline. Any instruction in the Executation which depended on the output of an instruction in the writeback stage would be lost if the back end of the pipelined advanced. The solution is to stall the whole pipeline.
