6299c0ef0b 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.

2f49ee18fe 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.

b52512b1ae D$ scope-specific coverage exclusions (I$ logic that never fires)
The InvalidateCache signal in the D$ is for I$ only, which
causes some coverage issues that need exclusion.

Another manual exclusion is due to the fact that D$ writeback, flush,
write_line, or flush_writeback states can't be cancelled by a flush,
so those transistions are excluded.

There is some other small stuff to review (logic simplification,
or an exclusion pragma if removing the redundent logic would
make it harder to understand the code, as is the case in the
FlushAdrCntEn assign statement, in my opinion).
