ImmutableSet/ImmtuableMap/ImmutableList APIs.
Along the way, clean up some method names in
the static analyzer so that they are more
descriptive and/or start with lowercase letters.

analyzing loads/stores, we lose the location SVal, which makes it difficult to recover in some cases (e.g., for post diagnostics). This is prep for pending changes to GRExprEngine.

we now may have identical states with different analysis context.
Set the right AnalysisContext in state when entering and leaving a callee.
With both of the above changes, we can pass the test case.

(1) libAnalysis is a generic analysis library that can be used by
Sema. It defines the CFG, basic dataflow analysis primitives, and
inexpensive flow-sensitive analyses (e.g. LiveVariables).
(2) libChecker contains the guts of the static analyzer, incuding the
path-sensitive analysis engine and domain-specific checks.
Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.
This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker. More changes pending. :)
This change also exposed a layering violation between AnalysisContext
and MemRegion. BlockInvocationContext shouldn't explicitly know about
BlockDataRegions. For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet). We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.
