Summary:
This moves the data collection macro calls for Stmt nodes
to lib/AST/StmtDataCollectors.inc
Users can subclass ConstStmtVisitor and include StmtDataCollectors.inc
to define visitor methods for each Stmt subclass. This makes it also
possible to customize the visit methods as exemplified in
lib/Analysis/CloneDetection.cpp.
Move helper methods for data collection to a new module,
AST/DataCollection.
Add data collection for DeclRefExpr, MemberExpr and some literals.
