6921: Higher-ranked trait bounds for where clauses r=flodiebold a=Veykril
There is a slight problem with this which is also noted in a FIXME now but `LifetimeParameters` of these ForLifetime where clauses allocate the lifetimes in the corresponding arena as if they were lifetimes of the item itself and not just the clause they belong to. I wasn't entirely sure what I could do about this but given nothing really uses lifetimes like that currently I figured it might be fine? Open to suggestions for that problem.

6901: Temp fixes panic caused by no ast for proc-macro r=maklad a=edwin0cheng
There are some panic when hover/goto definition for proc-macro. It is because in current design, we don't have `ast-node` for proc-macro and then it trigger [this](479d1f7eec/crates/hir/src/has_source.rs (L116)) line to panic.
This PR is a temp fix for all of these similar to bd4c352831/crates/completion/src/render/macro_.rs (L42)

We used to have `Def` suffix for all symbols, but we moved off from
that. `FunctionDef` isn't better than `Function`. Looks like we've
forgot to change `Impl` though!
6896: Node-ify lifetimes r=jonas-schievink a=Veykril
Let's see if this passes the tests 🤞
Depends on https://github.com/rust-analyzer/ungrammar/pull/15

6897: Basic support for macros 2.0 r=jonas-schievink a=jonas-schievink
This adds support for (built-in-only) macros 2.0, and removes some hacks used for builtin derives, which are declared via macros 2.0 in libcore.
First steps for https://github.com/rust-analyzer/rust-analyzer/issues/2248.
Blocked on https://github.com/rust-analyzer/ungrammar/pull/16.

6818: Add Lifetimes to the HIR r=matklad a=Veykril
This doesn't handle resolve yet as I don't know yet how that will be used. I'll get to that once I start moving the lifetime reference PR to the hir.
This also adds a new `hir` name type for lifetimes and labels, `hir::LifetimeName`.

6553: Auto imports in completion r=matklad a=SomeoneToIgnore
![completion](https://user-images.githubusercontent.com/2690773/99155339-ae4fb380-26bf-11eb-805a-655b1706ce70.gif)
Closes https://github.com/rust-analyzer/rust-analyzer/issues/1062 but does not handle the completion order, since it's a separate task for https://github.com/rust-analyzer/rust-analyzer/issues/4922 , https://github.com/rust-analyzer/rust-analyzer/issues/4922 and maybe something else.
2 quirks in the current implementation:
* traits are not auto imported during method completion
If I understand the current situation right, we cannot search for traits by a **part** of a method name, we need a full name with correct case to get a trait for it.
* VSCode (?) autocompletion is not as rigid as in Intellij Rust as you can notice on the animation.
Intellij is able to refresh the completions on every new symbol added, yet VS Code does not query the completions on every symbol for me.
With a few debug prints placed in RA, I've observed the following behaviour: after the first set of completion suggestions is received, next symbol input does not trigger a server request, if the completions contain this symbol.
When more symbols added, the existing completion suggestions are filtered out until none are left and only then, on the next symbol it queries for completions.
It seems like the only alternative to get an updated set of results is to manually retrigger it with Esc and Ctrl + Space.
Despite the eerie latter bullet, the completion seems to work pretty fine and fast nontheless, but if you have any ideas on how to make it more smooth, I'll gladly try it out.

6251: Semantic Highlight: Add Callable modifier for variables r=matklad a=GrayJack
This PR added the `HighlightModifier::Callable` variant and assigned it to variables and parameters that are fn pointers, closures and implements FnOnce trait.
This allows to colorize these variables/parameters when used in call expression.
6310: Rewrite algo::diff to support insertion and deletion r=matklad a=Veykril
This in turn also makes `algo::diff` generate finer diffs(maybe even minimal diffs?) as insertions and deletions aren't always represented as as replacements of parent nodes now.
Required for #6287 to go on.

Declaration names sounds like a name of declaration -- something you
can use for analysis. It empathically isn't, and is just a label
displayed in various UI. It's important not to confuse the two, least
we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).
