To simplify clients, have the cursorinfo result be consistent whether
requesting a symbol within the current module or not, ie. do not skip
adding the module name.
Resolves rdar://77003299
Currently, SourceKit always implicitly sends diagnostics to the client after every edit. This doesn’t match our new cancellation story because diagnostics retrieval is no request and thus can’t be cancelled.
Instead, diagnostics retrieval should be a standalone request, which returns a cancellation token like every other request and which can thus also be cancelled as such.
The indented transition path here is to change all open and edit requests to be syntactic only. When diagnostics are needed, the new diagnostics request should be used.
rdar://83391522
The key changes here are
- To keep track of cancellation tokens for all `ScheduledConsumer`s in `SwiftASTManager`
- Generate unique request handles for all incoming requests (`create_request_handle `), use these request handles as cancellation tokens and return them from the `sourcekitd_send_request` methods
- Implement cancellation with `sourcekitd_cancel_request` as the entry point and `SwiftASTManager::cancelASTConsumer` as the termination point
Everything else is just plumbing the cancellation token through the various abstraction layers.

* "description" for override completion is now annotatable
* "description" doesn't include attributes and decl introducer, but it
includes generic paramters, effects specifiers, result type clause,
and generic where clauses
* "name" now only include the name and the parameter names
* "sourcetext" should be the same

When a range is a single expression/statement/decl or part of
expression, also return cursor based refactorings for the start of the
range.
This is a stop gap until the available refactorings are properly fixed
to be more lenient in general - the current fix is a little odd as eg.
if all of `foo.bar()` is selected, rename will be returned as an
available refactoring for `foo`. Still an improvement over completely
missing cursor based refactorings, however.
Resolves rdar://82060063
For more fine grained annoations. For now, it's handled as the same as
'Keyword' name kind.
Fix an issue where 'extension' wasn't marked as "keyword".
Also, move 'static' priting out of 'SkipIntroducerKeywords' guard
because 'static' is not an declaration introducer.

During a cursor info request, the resolved offset was mapped to line and
column using the buffer inside `SwiftDocumentSyntaxInfo`.
However, prior to 54683ca607,
`editorReplaceText` was not updating the syntax info. This meant that
snapshots would be more up to date than the buffer in the syntax info,
allowing for the possibility of an invalid offset.
While 54683ca607 would also fix this,
snapshots actually have a `getLineAndColumn` anyway. Use that instead of
grabbing the buffer from syntax info.

If the compiler arguments have errors in them (e.g. because a file with the same name is used twice), we can often still fulfill SourceKit requests because the compiler argument errors are only relevant for later stages of the compilation process.
Instead of bailing out early, do a best effor retrieving the compiler arguments that are valid and ignoring the errors.

Have SourceKit return locations for symbols outside of the current
module as well. Callsites of location and comment information should
explicitly disable retrieving serialized information where performance
is a concern.
Resolves rdar://75582627
.swiftsourceinfo files contain the serialized location for declarations.
Use this when outputting locations in cursor info so that clients need
not perform an extra index lookup for external modules.
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.
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.
Resolves rdar://75385556
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.

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"
},
...
]
}
Resolves rdar://problem/73904365
Adds a new 'key.retrieve_symbol_graph' option to the request. When set to 1 it
includes the JSON for a SymbolGraph containing a single node for the symbol at
the requested position.
This also extends the SymbolGraph library with a new entry point to get a graph
for a single symbol, and to additionally support type substitution to match the
existing CursorInfo behavior (e.g. so that when invoked on `first` in
`Array<Int>().first`, the type is given as `Int?` rather than `Element?`).

This attribute allows to define a pre-specialized entry point of a
generic function in a library.
The following definition provides a pre-specialized entry point for
`genericFunc(_:)` for the parameter type `Int` that clients of the
library can call.
```
@_specialize(exported: true, where T == Int)
public func genericFunc<T>(_ t: T) { ... }
```
Pre-specializations of internal `@inlinable` functions are allowed.
```
@usableFromInline
internal struct GenericThing<T> {
@_specialize(exported: true, where T == Int)
@inlinable
internal func genericMethod(_ t: T) {
}
}
```
There is syntax to pre-specialize a method from a different module.
```
import ModuleDefiningGenericFunc
@_specialize(exported: true, target: genericFunc(_:), where T == Double)
func prespecialize_genericFunc(_ t: T) { fatalError("dont call") }
```
Specially marked extensions allow for pre-specialization of internal
methods accross module boundries (respecting `@inlinable` and
`@usableFromInline`).
```
import ModuleDefiningGenericThing
public struct Something {}
@_specializeExtension
extension GenericThing {
@_specialize(exported: true, target: genericMethod(_:), where T == Something)
func prespecialize_genericMethod(_ t: T) { fatalError("dont call") }
}
```

This function used to perform an unqualified lookup without a source
location, to either find top-level members or members of a type.
Since this form of unqualified lookup is no longer supported, let's
instead explicitly call lookupInModule() or lookupQualified(),
depending on whether we're looking inside a type or not.
We weren't printing memberwise inits, shorthand arguments (e.g. $0, $1), and
other implicit decls, so cursor info would give empty annotated decl and fully
annotated decl fields for them.
Resolves rdar://problem/58929991
We would previously hide the protocol, its extensions and members, but the '_'
prefix really just means the protocol itself isn't intended for clients, rather
than its members.
This also adds support for 'fully_annotated_decl' entries in doc-info for
extensions to be consistent with every other decl, and removes the
'fully_annotated_generic_signature' entry we supplied as a fallback.
Also fixes several bugs with the synthesized extensions mechanism:
- The type sustitutions applied to the extension's requirements were computed
using the extension itself as the decl context rather than the extension's
nominal. The meant the extension's requirements themselves were assumed to
hold when determining the substitutions, so equality constraints were always
met. Because of this extension members were incorrectly merged with the base
nominal or its extensions despite having additional constraints.
- Types within the requirements weren't being transformed when printed (e.g.
'Self.Element' was printed rather than 'T') both in the interface output and
in the requirements list. We were also incorrectly printing requirements
that were already satisfied once the base type was subsituted in.
- If both the protocol extension and 'enabling' extension of the base nominal
that added the protocol conformance had conditional requirements, we were
only printing the protocol extension's requirements in the synthesized
extension.
- The USR and annotated decl output embedded in the 'key.doc.full_as_xml'
string for synthesized members were printed to match their original context, rather than
the synthesized one.

This change makes us treat it exactly as we do 'init'. We don't allow renaming the base name,
and don't fail if the basename doesn't match for calls.
Also:
- explicit init calls/references like `MyType.init(42)` are now reported with
'init' as a keywordBase range, rather than nothing.
- cursor info no longer reports rename as available on init/callAsFunction
calls without arguments, as there's nothing to rename in that case.
- Improved detection of when a referenced function is a call (rather than
reference) across syntactic rename, cursor-info, and indexing.
