Mark imported `@completionHandlerAsync` attrs as
implicit, which avoids printing them in generated
interfaces. And for the sake of completion,
serialize the implicit bit in case it's used
elsewhere in the future.
To make sure we continue to print
`@completionHandlerAsync` attributes explicitly
written by the user in Swift, add a SourceKit
interface test.

struct Foo {
init(_ arg1: String, arg2: Int) {}
init(label: Int) {}
}
func test(strVal: String) {
_ = Foo(<HERE>)
}
In this case, 'strVal' was prioritized because it can use as an argument
for 'init(_:arg2:)'. However, argument labels are almost always
preferable, and if the user actually want 'strVal', they can input a few
characters to get it at the top. So we should always prioritize call
argument patterns.

In a mixed Objective-C / Swift module, we have a Clang module overlay that’s a Source file, not a serialized AST as is currently assumed. That assumption caused a crash when retrieving the symbol graph as part of a cursor info request to SourceKit, which was invoked on a method defined in the Objective-C part of the module.
To fix the crash, recursively use the same logic that already exists to serialize a module to also serialize the clang overlay module since that function alreayd correctly handles the distinction between source files and serialized ASTs.

Don’t record a `memberOf` relationship if we couldn’t look up the target, e.g. because the member is declared in an extension whose extended type doesn’t exist.

In the following test case, we are crashing while building the generic signature of `someGenericFunc`, potentially invoked on `model` in line 11.
```swift
struct MyBinding<BindingOuter> {
func someGenericFunc<BindingInner>(x: BindingInner) {}
}
struct MyTextField<TextFieldOuter> {
init<TextFieldInner>(text: MyBinding<TextFieldInner>) {}
}
struct EncodedView {
func foo(model: MyBinding<String>) {
let _ = MyTextField<String>(text: model)
}
}
```
Because we know that `model` has type `MyBinding<TextFieldInner>`, we substitute the `BindingOuter` generic parameter by `TextFieldInner`. Thus, `someGenericFunc` has the signature `<TextFieldInner /* substitutes BindingOuter */, BindingInner>`. `TextFieldInner` and `BindingOuter` both have `depth = 1`, `index = 0`. Thus the verification in `GenericSignatureBuilder` is failing.
After discussion with Slava, the root issue appears to be that we shouldn’t be calling `subst` on a `GenericFunctionType` at all. Instead we should be using `substGenericArgs` which doesn’t attempt to rebuild a generic signature, but instead builds a non-generic function type.
--------------------------------------------------------------------------------
We slightly regress in code completion results by showing two `collidingGeneric` twice in the following case.
```swift
protocol P1 {
func collidingGeneric<T>(x: T)
}
protocol P2 {
func collidingGeneric<T>(x: T)
}
class C : P1, P2 {
#^COMPLETE^#
}
```
Previously, we were representing the type of `collidingGeneric` by a generic function type with generic param `T` that doesn’t have any restrictions. Since we are now using `substGenericArgs` instead of `subst`, we receive a non-generic function type that represents `T` as an archetype. And since that archetype is different for the two function signatures, we show the result twice in code completion.
One could also argue that showing the result twice is intended (or at least acceptable) behaviour since, the two protocol may name their generic params differently. E.g. in
```swift
protocol P1 {
func collidingGeneric<S>(x: S)
}
protocol P2 {
func collidingGeneric<T>(x: T)
}
class C : P1, P2 {
#^COMPLETE^#
}
```
we might be expected to show the following two results
```
func collidingGeneric<S>(x: S)
func collidingGeneric<T>(x: T)
```

Since 9ba892c we always transform `CurrentType` in `ASTPrinter` to be an interface type.
This causes issues when the variable type is a generic parameter type. Previously we had `CurrentType` set to a `PrimaryArchetypeType`. With the fix in d93ae06, we are mapping the archetype out of context to a `GenericParamType`. A `GenericParamType`, however, can’t have members, so we’re hitting an assertion when creating a `TypeTransformContext`. Since the entire type transformation in `printTransformedTypeWithOptions` is only affecting type members, we should be able to safely skip over the transformation if `CurrentType` can’t have any members.

The diagnosticc engine is keeping track of state which might modify parsing/typechecking behaviour. In the added test case the `fatalErrorOccurred` flag was during the first completion. The flag was still `true` for the second completion, causing parsing/typechecking to behave slightly differently. Because of this, the ExprRewriter failed when applying a constraint system solution, not properly cleaning up its `ExprStack`.
This PR tackles both issues:
1) Reset the `hadError` flags in the diagnostics engine
2) Clean up the `ExprRewriter`’s `ExprStack` when rewriting a target fails.
Either of these changes fixes the crash in the test case but I think both could manifest through different code paths in different scenarios.

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.

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

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.
