5612f30029 Cacheway Exclude FlushStage=1 when SetValidWay=1 
We determined that this case is not hit even for i$, so this
case is also excluded separately for i$. It could be a better
idea to remove the ~FlushStage check completely (if we're sure).

My reasoning for this one is written as a comment in the exclusion
script: since a pipeline stall is asserted by the cache in the fetch
stage (which happens before going into the WRITE_LINE state and
asserting SetValidWay), there seems to be no way to trigger
a FlushStage (FlushW for D$) while the stallM is active.

857956ac1e Cacheway exclude SelFlush=0 while FlushWay=0 in FlushWayEn assign 
FlushWay is always 1 for one way, but by default it is only 1 for
way 0.

The logic that advances FlushWay to ways 1, 2, and 3 only does so
on a subset of conditions that SelFlush is high (in cachefsm), so
this is unreachable for cachways 1-3.
