SmallPtrSet< const DeclRefExpr *, 16 >	constReferenceDeclRefExprs (const VarDecl &VarDecl, const Stmt &Stmt, ASTContext &Context)
	Returns set of all `DeclRefExprs` to `VarDecl` within `Stmt` where `VarDecl` is guaranteed to be accessed in a const fashion.

bool	isOnlyUsedAsConst (const VarDecl &Var, const Stmt &Stmt, ASTContext &Context)
	Returns true if all `DeclRefExpr` to the variable within `Stmt` do not modify it.

SmallPtrSet< const DeclRefExpr *, 16 >	allDeclRefExprs (const VarDecl &VarDecl, const Stmt &Stmt, ASTContext &Context)
	Returns set of all `DeclRefExprs` to `VarDecl` within `Stmt`.

SmallPtrSet< const DeclRefExpr *, 16 >	allDeclRefExprs (const VarDecl &VarDecl, const Decl &Decl, ASTContext &Context)
	Returns set of all `DeclRefExprs` to `VarDecl` within `Decl`.

bool	isCopyConstructorArgument (const DeclRefExpr &DeclRef, const Decl &Decl, ASTContext &Context)
	Returns `true` if `DeclRefExpr` is the argument of a copy-constructor call expression within `Decl`.

bool	isCopyAssignmentArgument (const DeclRefExpr &DeclRef, const Decl &Decl, ASTContext &Context)
	Returns `true` if `DeclRefExpr` is the argument of a copy-assignment operator CallExpr within `Decl`.
