Issue Description

In Expr.__init__() and Stmt.__init__(), the IR node annotation is
always overwritten with the AST node source code annotation. In some
cases, it might be that self.ir_node.annotation is already set to a
meaningful annotation and that the AST node source code annotation is
empty or less meaningful.
