[ast] Always visit all AST nodes, even dead nodes We'll let the bytecode compiler and optimizing compilers deal with dead code, rather than the ast visitors. The problem is that the visitors previously disagreed upon what was dead. That's bad if necessary visitors omit parts of the code that the bytecode generator will actually visit. I did consider removing the AST nodes immediately in the parser, but that adds overhead and actually broke code coverage. Since dead code shouldn't be shipped to the browser anyway (and we can still omit it later in the bytecode generator), I opted for keeping the nodes instead.
