In `rustc`, the macro scope behave exactly the same as type and value scope. It is valid that macros, types and values having exact the same name, and a `use` statement will import all of them. This happened to module `alloc::vec` and macro `alloc::vec!`. So `Either` is not suitable here. There is a trap that not only does `#[macro_use]` import all `#[macro_export] macro_rules`, but also imports all macros `use`d in the crate root. In other words, it just _imports all macros in the module scope of crate root_. (Visibility of `use` doesn't matter.) And it also happened to `libstd` which has `use alloc_crate::vec;` in crate root to re-export `alloc::vec`, which it both a module and a macro. The current implementation of `#[macro_use] extern crate` doesn't work here, so that is why only macros directly from `libstd` like `dbg!` work, while `vec!` from `liballoc` doesn't. This PR fixes this. Another point is that, after some tests, I figure out that _`macro_rules` does NOT define macro in current module scope at all_. It defines itself in legacy textual scope. And if `#[macro_export]` is given, it also is defined ONLY in module scope of crate root. (Then being `macro_use`d, as mentioned above) (Well, the nightly [Declarative Macro 2.0](https://github.com/rust-lang/rust/issues/39412) simply always define in current module scope only, just like normal items do. But it is not yet supported by us) After this PR, in my test, all non-builtin macros are resolved now. (Hover text for documentation is available) So it fixes #1688 . Since compiler builtin macros are marked as `#[rustc_doc_only_macro]` instead of `#[macro_export]`, we can simply tweak the condition to let it resolved, but it may cause expansion error. Some critical notes are also given in doc-comments. <img width="447" alt="Screenshot_20190909_223859" src="https://user-images.githubusercontent.com/14816024/64540366-ac1ef600-d352-11e9-804f-566ba7559206.png"> Co-authored-by: uHOOCCOOHu <[email protected]>

| |/ | | | | | | | | | | | | | | | | | | | | | | This is to make debugging rust-analyzer easier. The idea is that `dbg!(krate.debug(db))` will print the actual, fuzzy crate name, instead of precise ID. Debug printing infra is a separate thing, to make sure that the actual hir doesn't have access to global information. Do not use `.debug` for `log::` logging: debugging executes queries, and might introduce unneded dependencies to the crate graph

Now it is quite accurate to resolve textual scoped macros. - Expand textual scoped macros in item and non-item place. - Support `#[macro_use]` on `mod`. - Textual scoped macros are collected into `nameres::ModuleScope`, so I think it makes #1727 easier to fix. - It is implemented in a simple way to `clone()` current scoped macro ids into sub-modules. Though only indices are cloned, it will still increase some resolving time. Well, I've not bench-marked yet. In my test with vscode extension, it can now successfully expand `dbg!` from `std` without `std::` prefix. "Goto definition" also works.

The clauses need to be wrapped in `FromEnv` clauses for that to work, which I didn't do before. - add some tests for closure inference already Co-authored-by: Florian Diebold <[email protected]>
