Component that require randomness should not share their randomness
source with other components to avoid simulation noise. For instance,
the branch predictor of one core should not impact the random
cache replacement policy of the cache of another core. This currently
happens as all components share a single random number generator.
This PR provides their own generators to relevant components, although
a couple components still use rand().
