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.
Explicitly instantiate the `CursorInfoData` instances when using it with
the default constructor rather than using the inline initializer list.
This is needed to build with C++14 mode. Provide a default value for
the `Optional` type in the structure which prevents a non-copy default
constructor from being synthesized. NFC.
Comparing to CharSourceRange, token stream is a better way because we can preserve comment information at the start of the range.

With the introduction of special decl names, `Identifier getName()` on
`ValueDecl` will be removed and pushed down to nominal declarations
whose name is guaranteed not to be special. Prepare for this by calling
to `DeclBaseName getBaseName()` instead where appropriate.
This changes `getBaseName()` on `DeclName` to return a `DeclBaseName`
instead of an `Identifier`. All places that will continue to be
expecting an `Identifier` are changed to call `getBaseIdentifier` which
will later assert that the `DeclName` is actually backed by an
identifier and not a special name.
For transitional purposes, a conversion operator from `DeclBaseName` to
`Identifier` has been added that will be removed again once migration
to DeclBaseName has been completed in other parts of the compiler.
Unify approach to printing declaration names
Printing a declaration's name using `<<` and `getBaseName()` is be
independent of the return type of `getBaseName()` which will change in
the future from `Identifier` to `DeclBaseName`
This makes us more lenient about what we accept for Objective-C
selectors by allowing you to include or not include the trailing colons.
We don't actually need that information, because we have access to the
declaration, so it was only being used for validation, which made the
API harder to use for clients that didn't carefully track zero vs
one-arg selector names.
Also remove the colons from the response, and instead add a bit to say
whether it is a zero-arg or one-arg selector. This makes the response
easier to use for clients that don't care about this information, and
more consistent with the change to the input.

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.

We were checking only for the specific loc of the declaration of the
param, but that didn't handle references to a local parameter inside the
body.

If a documentation comment has a - LocalizationKey: field, strip it
out of the documentation body and report it in cursor/doc info with
the key "key.localization_key".

This provides a stream utility for writing to a underlying string buffer multiple string pieces and retrieve them later as StringRef when the underlying buffer is stable.
