570e86afc3 Make CacheWay flush and dirty logic dependent on !READ_ONLY_CACHE 
To increase coverage. Read-only caches do not have flushes since
they do not have dirty bits.

3419ef3651 remove ClearValid from cache 
The cachefsm hardwired ClearValid logic to zero.
This signal might've been added to potentially add extra functionality
later. Unless that functionality is added, however, it negatively
impacts coverage. If the goal is to maximize coverage, this signal
should be removed and only added when it becomes necessary.

81125d3180 change i$ cachetagmem from ram1p1rwbe -> ram1p1rwe 
the byte write-enables were always tied high, so we can use
RAM without byte-enable to increase coverage.

782feb6161 turn off ce coverage for ram1p1rwe 
According to the textbook, the cache memory chip enable,
`CacheEn`, is only lowered by the cachefsm with it is in the ready
state and a pipeline stall is asserted.

For read only caches, cache writes only occur in the state_write_line
state. So there is no way that a write would happen while the chip
enable is low.

Removing the chip-enable check from this memory to increase coverage
would be a bad idea since if anyone else uses this ram, the behaviour
would be differently than expected. Instead, I opted to turn off
coverage for this statement. Since this ram, which does not have a
byte enable, is used exclusively by read-only caches right now, this
should not mistakenly exclude coverage for other cases, such as D$.
