3591: Support local macro_rules r=matklad a=edwin0cheng
This PR implement local `macro_rules` in function body, by adding following things:
1. While lowering, add a `MacroDefId` in body's `ItemScope` as a textual legacy macro.
2. Make `Expander::enter_expand` search with given `ItemScope`.
3. Make `Resolver::resolve_path_as_macro` search with `LocalItemScope`.
Fix#2181

There was a test for this, but it wasn't actually working because the first
recursive expansion failed. (The comma...)
Even with this limit, that test (when fixed) still takes some time to pass
because of the exponential growth of the expansions, so I disabled it and added
a different one without growth.
3384: fix#2377 super::super::* r=flodiebold a=JoshMcguigan
Thanks @matklad for the detailed explanation on #2377. I believe this fixes it.
One thing I'm not sure about is you said the fix would involve changing `crates/ra_hir_def/src/path/lower/lower.rs`, but I only changed `crates/ra_hir_def/src/path/lower/lower_use.rs`. I'm not sure what kind of test code I'd have to write to expose the issue in `lower.rs`, but I'd be happy to add it if you are able to provide additional guidance.

3260: Refactor how builtins are resolved r=matklad a=flodiebold
This fixes autocompletion suggesting e.g. `self::usize`. (I thought we had a bug for that, but I didn't find it.)

E.g. in `match x { None => ... }`, `None` is a path pattern (resolving to the
option variant), not a binding. To determine this, we need to try to resolve the
name during lowering. This isn't too hard since we already need to resolve names
for macro expansion anyway (though maybe a bit hacky).
Fixes#1618.
3062: Implement slice pattern AST > HIR lowering r=jplatte a=jplatte
WIP. The necessary changes for parsing are implemented, but actual inference is not yet. Just wanted to upload what I've got so far so it doesn't get duplicated :)
Will fix#3043
