be8e0eee1b 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.
