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
CloneDetection.cpp.

Move helper methods for data collection to a new module,

  AST/DataCollection.

Add data collection for DeclRefExpr, MemberExpr and some literals
