Since 9ba892c5af we always transform `CurrentType` in `ASTPrinter` to be an interface type.
This causes issues for variables that whose type is a protocol. Previously, when printing the type, we had `CurrentType` set to an `OpenedArchetypeType`. Now we replace the archetype by a `GenericTypeParamType`, which may not have members, so we are hitting an assertion in `ASTPrinter.cpp:270`.
To resolve this, replace any `OpenedArchetypeType`s with their protocol type before calling `mapTypeOutOfContext`.

Since 865e80f9c4 we are keeping track of internal closure labels in the closure’s type. With this change, wer are also serializing them to the swiftmodules.
Furthermore, this change adjusts the printing behaviour to print the parameter labels in the swiftinterfaces.

When printing a type in type through `ASTPrinter::printTransformedTypeWithOptions`, we are removing any contextual types by mapping the type out of context. However, when substituting `Self` (or any other type member) with their concrete type from `CurrentType`, we might re-introduce contextual types.
To fix this, make sure that `CurrentType` is always an interface type that has all contextual types removed.

Various uses of `getPresumedLineAndColumnForLoc` were likely added when
that function was the very misleading name `getLineAndColumn`. Change
these to use `getLineAndColumnForBuffer` instead where appropriate, ie.
we want the underlying file rather than the location to display to the
user.
There were also some cases where the buffer identifier had been swapped
to use the display name instead, under the assumption that the presumed
location was needed. Updated those as well.
SingleRawComment: Lines are only used when merging comments, where the
original location is fine to use.
Index: Doesn't store the file set in #sourceLocation, so using the
presumed line would end up pointing to a location that makes no sense.
Editor functionality: Formatting and refactoring are on the current
file. Using the presumed location would result in incorrect
replacements.
Repurpose mangling operator `Y` as an umbrella operator that covers new attributes on function types. Free up operators `J`, `j`, and `k`.
```
async ::= 'Ya' // 'async' annotation on function types
sendable ::= 'Yb' // @Sendable on function types
throws ::= 'K' // 'throws' annotation on function types
differentiable ::= 'Yjf' // @differentiable(_forward) on function type
differentiable ::= 'Yjr' // @differentiable(reverse) on function type
differentiable ::= 'Yjd' // @differentiable on function type
differentiable ::= 'Yjl' // @differentiable(_linear) on function type

If have a function that takes a trailing closure as follows
```
func sort(callback: (_ left: Int, _ right: Int) -> Bool) {}
```
completing a call to `sort` and expanding the trailing closure results in
```
sort { <#Int#>, <#Int#> in
<#code#>
}
```
We should be doing a better job here and defaulting the trailing closure's to the internal names specified in the function signature. I.e. the final result should be
```
sort { left, right in
<#code#>
}
```
This commit does exactly that.
Firstly, it keeps track of the closure's internal names (as specified in the declaration of `sort`) in the closure's type through a new `InternalLabel` property in `AnyFunctionType::Param`. Once the type containing the parameter gets canonicalized, the internal label is dropped.
Secondly, it adds a new option to `ASTPrinter` to always try and print parameter labels. With this option set to true, it will always print external paramter labels and, if they are present, print the internal parameter label as `_ <internalLabel>`.
Finally, we can use this new printing mode to print the trailing closure’s type as
```
<#T##callback: (Int, Int) -> Bool##(_ left: Int, _ right: Int) -> Bool#>
```
This is already correctly expanded by code-expand to the desired result. I also added a test case for that behaviour.
use-swift-source-info.swift is checking that the .swiftsourceinfo file
is being used when OptimizedForIDE is false by checking the location
output from a cursor info request.
It also checks that the module name is there, which it should be the
result is in a different file. There was previously a bug where it
*wasn't* added when a location was added (which was valid before
.swiftsourceinfo was used). The test has always worked since it was
modified in the fix to that bug, but some weirdness caused the change
and test to be out of sync (possibly the result of merges between main
and next branches).
The new line is the language, which was added after it was disabled (and
hence missed being updated).
`SemaAnnotator` walks the tree in source order with respect to the source ranges *excluding* attributes, but `RangeResolver` considers attributes part of their declaration. Thus they disagree on what “walking in source order means”. `SemaAnnotator` will visit the attributes *before* the decl they are on, while `RangeResolver` as currently implemented expects them *as part of* the decl they are on.
Thus, for the purpose of `RangeResolver`, we need to assume that nodes are visited in arbitrary order and we might encounter enclosing nodes after their children.
Thus, when we find a new node, remove all nodes that it encloses from `ContainedASTNodes`.

Cursor info for a constructor would previously give the cursor info for
the containing type only. It now also adds cursor info for the
constructor itself in a "secondary_symbols" field.
Refactor `passCursorInfoForDecl` to use a single allocator rather than
keeping track of positions in a buffer and assigning everything at the
end of the function.
Refactor the various available refactoring gathering functions to take a
SmallVectorImpl and to not copy strings where they don't need to.

Adds two new fields to the cursor info response:
1. is_dynamic: whether a call is dynamic
2. receivers: receivers of the call (USRs)
Users of the CursorInfo request can use "is_dynamic" to decide whether
to lookup overrides or not, and then the "receivers" as the starting
point of the lookup.

The end location of an attribute used to point to the next token after the attribute's content, which is the closing parenthesis in valid Swift code. But when the parenthesis is missing, it points to the next token, which is most likely no longer part of the attribute.
Fix by parsting the closing parenthesis (conditionally) first and using the location of last token parsed for the attribute (`PreviuosLoc`) as the attribute range's end location.

Including the symbol itself means if clients want the same info we provide
about the parent contexts for the symbol under the cursor they won’t need to
parse it out from the symbol graph json.

`visitTopLevelCodeDecl` ignored the `Stmt` visit returning a nullptr.
This caused the `walkToDeclPost` to run for the `TopLevelCodeDecl` and
thus an imbalance in the `RangeResolver` pre and posts (since none of
the children would have their `walkTo*Post` called).
This was originally incorrectly fixed while assuming that the
`walkTo*Post` are called regardless of whether the children were visited
or not. Those changes have been reverted - fixing an imbalance in
`ExtDecls` in `SemaAnnotator`.
Added a test case for the `ExtDecls` imbalance which can occur while an
extension is being added.

This patch updates the `actor class` spelling to `actor` in almost all
of the tests. There are places where I verify that we sanely handle
`actor` as an attribute though. These include:
- test/decl/class/actor/basic.swift
- test/decl/protocol/special/Actor.swift
- test/SourceKit/CursorInfo/cursor_info_concurrency.swift
- test/attr/attr_objc_async.swift
- test/ModuleInterface/actor_protocol.swift
When the SymbolGraph json is requested via (key.retrieve_symbol_graph: 1) this adds
a new field in the response that lists all the parent contexts of the symbol under
the cursor with their symbol graph kind and name, and their USR:
key.parent_contexts: [
{
key.kind: "swift.struct",
key.name: "Parent",
key.usr: "s:27cursor_symbol_graph_parents6ParentV"
},
...
]
}
