Removes nodrop and extra arrayvec
We have an extra crossbeam-queue and crossbeam-utils left but those should
drop once rayon accepts https://github.com/rayon-rs/rayon/pull/704
2179: Use HirDatabase to compute `is_deprecated` r=matklad a=martskins
This PR fixes#2167 by introducing `attributes_query` and adding `fn attrs(&self, def: crate::AttrDef) -> Option<Arc<[Attr]>>;` to the `DefDatabase` trait.
I'm a little concerned about the two spots in `attributes_query` where code is repeated, but I couldn't figure out a way to avoid that, so.. I welcome suggestions 😄

2173: MBE: Add TokenId shift in macro_rules r=matklad a=edwin0cheng
As discussed in #2169 , for fixing duplication TokenId during expansion :
> What we can do here is to re-number the tokens during expansion. Specifically:
> * when we create macro_rules, we note the highest id of the token we have as shift>
> * when we expand macro rules, if we need to output a token from definition, we just re-use its id
> * if we need to output a token from the argument, we increase its id by shift (so it's guaranteed to not to collide with anything from the definition)
> * finally, when we have a HirFileId of the expansion, we can look up the original value of shift and classify node to the arg/def by comparing it's id with shift.

This PR implement first 3 points of above solution.

2149: Handle IfLet in convert_to_guarded_return. r=matklad a=krk
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/2124
I could not move the cursor position out of `let`:
`le<|>t` vs `let<|>`.
Also, please suggest extra test cases.
