8796: internal: rewrite `#[derive]` removal to be based on AST (take 2) r=jonas-schievink a=jonas-schievink
Second attempt of https://github.com/rust-analyzer/rust-analyzer/pull/8443, this uses syntactical attribute offsets in `hir_expand`, and changes `attr.rs` to make those easy to derive.
This will make it easy to add similar attribute removal for attribute macros, unblocking them.

8800: feat: Make "pull assignments up" assist work in more cases r=Jesse-Bakker a=Jesse-Bakker
Fixes#8771
Co-authored-by: Jesse Bakker <github@jessebakker.com>
This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead
of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range
array declarations are unsupported as before.
I don't know why a bunch of our rustc tests had single quotes inside
strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's
bad? Maybe something in a nightly?
8794: Give MergeBehaviour variants better names r=Veykril a=Veykril
I never really liked the variant names I gave this enum from the beginning and then I found out about rustfmt's `imports_granularity` config:
> imports_granularity
>
> How imports should be grouped into use statements. Imports will be merged or split to the configured level of granularity.
>
> Default value: Preserve
> Possible values: Preserve, Crate, Module, Item
> Stable: No
I personally prefer using `crate` over `full` and `module` over last, they seem more descriptive. Keeping these similar between tooling also seems like a good plus point to me.
We might even wanna take over the entire enum at some point if we have a `format/cleanup imports` assists in the future which would probably want to also have the `preserve` and `item` options.

There's a tension between keeping a well-architectured minimal
orthogonal set of constructs, and providing convenience functions.
Relieve this pressure by introducing an dedicated module for
non-orthogonal shortcuts.
This is inspired by the django.shortcuts module which serves a similar
purpose architecturally.
8776: fix: fix unnecessary recomputations due to macros r=jonas-schievink a=jonas-schievink
This computes a macro's fragment kind eagerly (when the calling file is still available in parsed form) and stores it in the `MacroCallLoc`. This means that during expansion we no longer have to reparse the file containing the macro call, avoiding the unnecessary salsa dependencies (https://github.com/rust-analyzer/rust-analyzer/pull/8746#issuecomment-834776349).
Marking as draft until I manage to find a test for this problem, since for some reason `typing_inside_a_function_should_not_invalidate_expansions` does not catch this (which might indicate that I misunderstand the problem).
I've manually confirmed that this fixes the issue described in https://github.com/rust-analyzer/rust-analyzer/pull/8746#issuecomment-834776349:
```
7ms - parse_query @ FileId(179)
12ms - SourceBinder::to_module_def
12ms - crate_def_map:wait
5ms - item_tree_query (1 calls)
7ms - ???
```
