To controls the lifetime of CompilerInstance within CompletionIntance.
- Prevent from using the same CompilerInstance from multiple completion
requests
- Separate the stacktrace between "fast" and "normal" completions
- Further code consolidation between various completion-like requests
- Introduce ide::CompletionInstance to manage CompilerInstance
- `CompletionInstance` vends the cached CompilerInstance when:
-- The compiler arguments (i.e. CompilerInvocation) has has not changed
-- The primary file is the same
-- The completion happens inside function bodies in both previous and
current completion
-- The interface hash of the primary file has not changed
- Otherwise, it vends a fresh CompilerInstance and cache it for the next
completion

Structurally prevent a number of common anti-patterns involving generic
signatures by separating the interface into GenericSignature and the
implementation into GenericSignatureBase. In particular, this allows
the comparison operators to be deleted which forces callers to
canonicalize the signature or ask to compare pointers explicitly.
Propagates the VFS to the SemanticInfo that gets used when then
original editor.open is syntactic only.
Removes unnecessary filesystem arg (get filesystem from class field
instead).
Adds test for the VFS being propagated into the SemanticInfo.
Refactors test/SourceKit/CursorInfo/injected_vfs.swift to use
-print-raw-response for all its tests, for consistency.
The invocation options are not an appropriate place to put this state,
since it can change between requests. This moves it to the editor
document, allowing us to change the specific VFS instance without
causing a rebuild (unless the contents/timestamps for a dependency
change).
This has been an unnecessary code path for a long time now and should be removed particularly because it triggers wasteful `stat` calls.

Previously, requests would fail silently by returning an empty struct
in the response.
With this change, responses will properly report fail with the internal
error.

Extend the support for single-expression closures to handle
single-expression functions of all kinds. This allows, e.g.
func foo() -> MyEnum { .<here> }
to complete members of `MyEnum`.
The client usually cares about a subset of all expressions. A way to differentiate
them is by the protocols these expressions' types conform to. This patch allows
the request to add a list of protocol USRs so that the response only includes those
interested expressions that conform to any of the input protocols.
We also add a field to the response for each expression type to indicate the
conforming protocols names that were originally in the input list.
When an empty list of protocol USRs are given, we report all expressions' types
in the file like the old behavior.

Members of an @objcMembers context previous had implicit @objc attributes, but
now don't (possibly because of the request evaluator changes?). This updates the
output of sourcekitd's 'index' request to act as if they still had implicit
@objc attributes on them for compatibility.
Resolves rdar://problem/48140265
This request collects the types of all expressions in a source file after type checking.
To fulfill this task, the client must provide the path to the Swift source file under
type checking and the necessary compiler arguments to help resolve all dependencies.
Request:
{
<key.request>: (UID) <source.request.expression.type>,
<key.sourcefile>: (string) // Absolute path to the file.
<key.compilerargs>: [string*] // Array of zero or more strings for the compiler arguments,
// e.g ["-sdk", "/path/to/sdk"]. If key.sourcefile is provided,
// these must include the path to that file.
}
Response:
{
<key.printedtypebuffer>: (string) // A text buffer where all expression types are printed to.
<key.expression_type_list>: (array) [expr-type-info*] // A list of expression and type
}
expr-type-info ::=
{
<key.expression_offset>: (int64) // Offset of an expression in the source file
<key.expression_length>: (int64) // Length of an expression in the source file
<key.type_offset>: (int64) // Offset of the printed type of the expression in the printed type buffer
<key.type_length>: (int64) // Length of the printed type of the expression in the printed type buffer
}

`source.request.conformingmethods` is a new SourceKit request which
receives a source position and a list of protocol namses, returns a list
of methods whose return type conforms to the requested protocols.
rdar://problem/44699573
This is a new SourceKit request which receives a position in the source
file, returns possible expected types and their members which can be
referenced by "implicit member expression" syntax.
Addressing review feedback: this avoids calling shared_from_this() from
outside the implementation. Note: it is not possible to use private
inheritance of enable_shared_from_this to prevent this issue in general,
because enabled_shared_from_this relies on the shared_ptr constructor
being able to detect that the type has this inheritance, which means it
must be public.
While the SwiftLangSupport doesn't currently outlive the global context
it clarifies the ownership to just store the weak reference we care
about instead of referencing the owning context. In the future we may
want to ref-count the lang support, in which case we'd need to do this
to avoid a cycle anyway.
When the server shuts down we may still have outstanding async work to
build an AST, so use a shared_ptr + weak_ptr instead of unique_ptr +
unowned references.
If enabled using the environment variable
SOURCEKIT_INCREMENTAL_PARSE_VALIDATION, the incrementally parsed syntax
tree will be compared to the from-scratch parsing syntax tree. If they
differ a warning is emitted and log files showing the difference written
to a temporary directory.
