[analyzer] Do not step into statements while collecting function decls.
CallGraph's recursive visitor only needs to collect declarations; their
bodies will be processed later on. RecursiveASTVisitor will recurse on
the bodies if the definition is provided along with declaration.
Optimize, by not recursing on any of the statements.
