Allow #[rustc_builtin_macro = "name"].
This makes it possible to have both std::panic and core::panic as a builtin macro, by using different builtin macro names for each. Also removes SyntaxExtension::is_derive_copy, as the macro name (e.g. sym::Copy) is now tracked and provides that information directly.
