de93bd6937 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).

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.
