Siegfried Pammer 9aa0ddd37b Replace AST null-objects with nullable reference types With every optional slot nullable, the null-object pattern is dead. Generated non-nullable getters return the backing field directly, which surfaced a last tier of slots the decompiler legitimately leaves empty (omitted range operands, an implicitly-typed array creation, unnamed parameters, an unbound generic argument, and others) and flips them to nullable too. The machinery is then removed entirely: the per-node null classes, the .Null statics and VisitNullNode, AstNode.IsNull, the role null object, and Identifier.Null. AcceptVisitor becomes unconditionally generated, and consumers move from .IsNull to is null and from unconditional visits to ?.AcceptVisitor.
