Ted Kremenek 07343c02be For GRExprEngine::EvalBind() (and called visitors), unifiy StoreE and AssignE. Now StoreE (const Stmt*) represents the expression where the store took place, which is the assignment expression if it takes place in an assignment. This removes some conceptual dissidence as well as removes an extra parameter from the Checker::PreVisitBind() visitor. It also improves ranges and source location information in analyzer diagnostics.

Ted Kremenek 28ec56d7dd Improve the diagnostics for the UndefinedAssignmentChecker when an
uninitialized value is used in the LHS of a compound assignment.

Ted Kremenek d6b8708643 Split libAnalysis into two libraries: libAnalysis and libChecker.
(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.
