Program is now immutable*, and remains part of the public Tint interface. ProgramBuilder is the mutable builder for Programs, and is not part of the public Tint interface. ast::Builder has been folded into ProgramBuilder. Immutable Programs can be cloned into a mutable ProgramBuilder with Program::CloneAsBuilder(). Mutable ProgramBuilders can be moved into immutable Programs. * - mostly immutable. It still has a move constructor and move assignment operator - required for practical usage - and the semantic information on AST nodes is still mutable.
