Nicholas Nethercote ae5f67f9e8 Remove the T::VISIT_TOKENS test in visit_mac_args.
The two paths are equivalent -- they both end up calling `visit_expr()`.
I have kept the more restrictive path, the one that requires that
`token` be an expression nonterminal. (The next commit will simplify this
function further.)

The rustc_ast crate contains those things concerned purely with syntax that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).

For more information about how these things work in rustc, see the rustc dev guide:
