ImmutableAnalysis abstraction for fetching the Eviction Advisor.
We model it as an analysis to decouple the user from the implementation insofar as dependencies on other analyses goes. The motivation for it being an immutable pass is twofold:
Because we need to offer additional services in 'development' mode, the implementations of this analysis need to implement RTTI support.

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.
