Adds a label / lifetime parameter to `ide_assists::handlers::extract_function::FlowKind::{Break, Continue}`, adds support for emitting labels to `syntax::ast::make::{expr_break, expr_continue}`, and implements the required machinery to let `extract_function` make use of them.
This does modify the external API of the `syntax` crate, but the changes there are simple, not used outside `ide_assists`, and, well, we should probably support emitting `break` and `continue` labels through `syntax` anyways, they're part of the language spec.
Closes#11413.
11107: Fix generic type substitution in impl trait with assoc type r=pnevyk a=pnevyk
Fixes#11045
The path transform now detects if a type parameter that is being substituted has an associated type. In that case it is necessary (or safe in general case) to fully qualify the substitution with a trait which the associated type belongs to.
This PR also fixes the previous wrong behavior of the substitution that could create an invalid tree `PATH_TYPE -> PATH_TYPE -> ...`.

Revert "Fix `impl_trait` function to emit correct ast"
This reverts commit 55a4813151.
Fix `impl_def_from_trait`
It now generates the correct `ast::Impl` using
`generate_trait_impl_text` and parses it to form the right node (copied
from the private fn 'make::ast_from_text').
10546: feat: Implement promote_local_to_const assist r=Veykril a=Veykril
Fixes#7692, that is now one can invoke the `extract_variable` assist on something and then follow that up with this assist to turn it into a const.

10440: Fix Clippy warnings and replace some `if let`s with `match` r=Veykril a=arzg
I decided to try fixing a bunch of Clippy warnings. I am aware of this project’s opinion of Clippy (I have read both [rust-lang/clippy#5537](https://github.com/rust-lang/rust-clippy/issues/5537) and [rust-analyzer/rowan#57 (comment)](https://github.com/rust-analyzer/rowan/pull/57#discussion_r415676159)), so I totally understand if part of or the entirety of this PR is rejected. In particular, I can see how the semicolons and `if let` vs `match` commits provide comparatively little benefit when compared to the ensuing churn.
I tried to separate each kind of change into its own commit to make it easier to discard certain changes. I also only applied Clippy suggestions where I thought they provided a definite improvement to the code (apart from semicolons, which is IMO more of a formatting/consistency question than a linting question). In the end I accumulated a list of 28 Clippy lints I ignored entirely.
Sidenote: I should really have asked about this on Zulip before going through all 1,555 `if let`s in the codebase to decide which ones definitely look better as `match` :P

Consider these expples
{ 92 }
async { 92 }
'a: { 92 }
#[a] { 92 }
Previously the tree for them were
BLOCK_EXPR
{ ... }
EFFECT_EXPR
async
BLOCK_EXPR
{ ... }
EFFECT_EXPR
'a:
BLOCK_EXPR
{ ... }
BLOCK_EXPR
#[a]
{ ... }
As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers
BLOCK_EXPR
STMT_LIST
{ ... }
BLOCK_EXPR
async
STMT_LIST
{ ... }
BLOCK_EXPR
'a:
STMT_LIST
{ ... }
BLOCK_EXPR
#[a]
STMT_LIST
{ ... }
