Yuki Okushi 3e735c6e93 Rollup merge of #80850 - m-ou-se:rustc-builtin-macro-name, r=petrochenkov ... Allow #[rustc_builtin_macro = "name"] This adds the option of specifying the name of a builtin macro in the `#[rustc_builtin_macro]` attribute: `#[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. This is needed to implement the edition-specific behaviour of the panic macros of RFC 3007. Also removes `SyntaxExtension::is_derive_copy`, as the macro name (e.g. `sym::Copy`) is now tracked and provides that information directly. r? ``@petrochenkov``		2021-01-10 16:56:05 +09:00
