Ben Clayton 971318f7a2 tint: Replace all remaining AST types with ast::Type ... This CL removes the following AST nodes: * ast::Array * ast::Atomic * ast::Matrix * ast::MultisampledTexture * ast::Pointer * ast::SampledTexture * ast::Texture * ast::TypeName * ast::Vector ast::Type, which used to be the base class for all AST types, is now a thin wrapper around ast::IdentifierExpression. All types are now referred to using their type name. The resolver now handles type resolution and validation of the types listed above based on the TemplateIdentifier arguments. Other changes: * ProgramBuilder has undergone substantial refactoring. * ProgramBuilder helpers for type inferencing is now more explicit. Instead of passing 'nullptr', a new 'Infer' template argument is passed. * ast::CheckIdentifier() is used for more tests that check identifiers, including types.
