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$.
