4cbb9bcec6 refactor cachefsm to get full coverage 
I had to exclude i$ states in coverage-exclusions-rv64gc.do,
but it's referred to by scope, which should be pretty robust

a1bbcd5e8a Coverage and readability improvements to LRUUpdate logic 
The genvar stuff was switched to readable names to make it easier
to understand for the first time. In the LRUUpdate logic for loop,
a special case was added for simpler logic in the case of the root
node, to hit coverage.

7c9f68e984 Remove FlushStage Logic from CacheLRU 
For coverage.

LRUWriteEn is gated by FlushStage in cache.sv,
so removing the signal completely avoids future confusion.

Update cache.sv to reflect cacheLRU edit.

68a01cb0f8 Exclude (FlushStage & SetValidWay) condition for RO caches 
Spent a long time trying to find a way to see if this condition was
possible, only to become relativly convinced that it isn't.
Basically, since RO cache writes only happen after a long period of
stall for the bus access, there's no way a flushD can be active
at the same time as a RO cache write. TrapM causes a FlushD, but
interrupts are gated by the "commited" logic and the exception
pipeline stalls.

I feel like its worth keeping the logic to be safe
so I've chosen to exclude it rather than explicitely remove it.
