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.
With more options coming for incremental syntax parsing, the list of
arguments will grow way to large and unhandy, so just extract them into
one common struct.
Disable the sanitizers and code coverage when building a swift
invocation for the purpose of collecting diagnostics.
This should speed up diagnostic generation and reduce exposure to
compiler bugs.

... instead of an array of compiler arguments. This is good enough
for seeing what's going on, and it saves significant time for long
argument strings, because it doesn't create and destroy so many
xpc strings, and more of the string copying that happens is on a large
contiguous string instead of many small strings.

This code was an experiment in how to collect information after a crash,
that did not end up being used. It's unclear how much it has bitrotted
at this point, since it has no tests and was not designed with automated
testing in mind. Parts of it interfere with some changes I want to make
to the underlying tracing mechanism, so I am finally removing it. This
also lets us remove the buffer copying in the parts of tracing used by
the compile notifications, improving performance.

Before this patch, we have one flag (KeepSyntaxInfo) to turn on two syntax
functionalities of parser: (1) collecting parsed tokens for coloring and
(2) building syntax trees. Since sourcekitd is the only consumer of either of these
functionalities, sourcekitd by default always enables such flag.
However, empirical results show (2) is both heavier and less-frequently
needed than (1). Therefore, separating the flag to two flags makes more
sense, where CollectParsedToken controls (1) and BuildSyntaxTree
controls (2).
CollectingParsedToken is always enabled by sourcekitd because
formatting and syntax-coloring need it; however BuildSyntaxTree should
be explicitly switched on by sourcekitd clients.

Before conditional conformances, the archetypes in conformance
extensions (i.e. extension Foo: SomeProtocol) were equivalent to those
in the type decl, with the same protocol bounds and so on. The code for
printing "synthesized" members relied on this fact. This commit teaches
that code to deal with archetypes in the conditional conformance
extension when required.
Fixes rdar://problem/36553066 and SR-6930.
... and add a few basic statistics about the number of requests, ASTs
built, etc. The Statistic type is loosely based on the one from LLVM,
but suitable for using without DEBUG macros and using SourceKit UIdents
to identify the statistic. The easiest way to add a new statistic is to
add it to SwiftStatistics.def in the SwiftLangSupport.
When using completion options that will allow the lone "." completion,
provide that result when in contexts that expect an enum type. Note:
this is a crappy approximationg for whether the type can have "implicit
member expression" syntax, since uninhabited enums should not support
it, and many non-enum types should. However, it is currently expensive
to compute the accurate answer and this approximation is good enough for
some clients.

The OncePerASTToken machinery lets us automatically cancel "stale"
requests after a new one comes in. This avoid wasting time processing
requests that have been superceded, which is common for cursor-info, but
sometimes you really want to get results even later, so this commit adds
a way to opt out of the cancellation.
Incidentally, disable cancellation of name translation, which doesn't
really make sense and no one should be relying on that.

Extensive cross-language tooling support needs to bridge decl names between two different languages more freely. This SourceKit request is designed to translate Objc names to Swift names and vice versa. Working similarly to cursor-info requisition, the name translation request requires a Swift reference to a Swift/Clang decl, and the preferred name to translate from, and language kind that the given name belongs to. If the translation succeeds, SourceKit service responds with the corresponding name than belongs to the other kind of language.
Newly introduced keys:
“key.namekind": “source.lang.name.kind.objc” | "source.lang.name.kind.swift"
“key.basename”: “name"
“key.argnames”: [“name"]
“key.selectorpieces”: [“name[:]"]
This commit only implements translation from Objc to Swift.
Like cursor-info, range info (""source.request.cursorinfo"") answers some
questions clients have for a code snippet under selection, for instance, the type of a selected
expression. This commit implements this new quest kind and provides two
simple information about the selected code: (1) the kind of the
snippet, currently limited to single-statement and expression; and (2)
the type of the selected expression. Gradually, we will enrich the
response to provide more insight into the selected code snippet.
This patch allows SourceKit to generate the interface for a given type specified by its mangled name.
Type interface is refined decl printing with type parameters localized and unusable members hidden.
Required field:
"key.request": "source.request.editor.open.interface.swifttype"
"key.usr": the mangled name of the given type.
Typically, users jump to type-specific interface from a member of that type, for
instance, a.getSomething(). To generate the interface, we need to report the USR
of the container type of "getSomething()", which is the USR for the type of a,
when cursor info is requested for this function call.
The mangled name of the type is identical to those for debugger. These
mangled names allow us to reconstruct the type from AST and generate interface
specifically for that type.

The goal is to be able to move the core IndexSwiftASTWalker code out of
SourceKit, leaving only the serialization bits behind.
Mostly this replaces some direct uses of UIdent strings with explicit
enums, and then adds the translation code to produce those enums and to
convert them into UIdents in SourceKit.

Moved getTrimmedTextForLine & getExpandedIndentForLine
This help reduce the coupling to SwiftEditor Document and allows us
to format any text, whether or not is currently in an editor doc.
Move FormatContext & FormatWalker into new file.
Move CodeFormatOptions out of SwiftEditorDocument.
Move functions getTrimmedLineOffset & getLineOffset
out of SwiftEditor Document.
Rename Offset of Line functions
Declaring that the get the offset of some line index is more clear.
This eventually calls the code from ReconstructType to try to find the
Decl for a USR. For now, only works in a file, not a generated
interface.

Also expose the printing function as a SwiftLangSupport static method.
Ideally we could move this into libIDE, but it currently depends on the
UIdent visitor to get decl-specific tag names and it's not obvious how
we should hoist/abstract that out in a nice way.
