Introduces the new DeclarationsArrayBuilder and adds it to the
EditorConsumer. Declaration info always includes a kind, offset, and
length, and includes a USR where applicable.
As the USR is already available for editor.open.interface type requests,
this doesn't compute any new information, it just exposes more of what's
there already.
This adjusts the tests for the difference between line endings on
different platforms. Windows uses CRLF while most Unicies use LF. This
was exposed during the update to the new LLVM snapshot.
...and remove the option. This is ~technically~ CLI-breaking because
Swift 5 shipped this as a hidden driver option, but it wouldn't have
/done/ anything in Swift 5, so I think it's okay to remove.
Note that if a parseable interface (.swiftinterface) and a binary
interface (.swiftmodule) are both present, the binary one will still
be preferred. This just /allows/ parseable interfaces to be used.

In addition to capturing more detailed preprocessor info, the
DetailedPreprocessorRecord option sets the clang module format to 'raw'
rather than the default 'object'. Sourcekitd doesn't link the code
generation libs, which it looks like the default 'object' format requires,
so it sets this option to true. The subinvocation generated when loading a
module from a .swiftinterface file still used the default prior to this
change though, so it would end up crashing sourcekitd.
This change sets the DetailedProccessorRecord option if the DetailedRecord
option is set on the preprocessor options of parent context's clang module
loader. This fixes interface generation crashing for modules that only have
a .swiftinterface file.

Rather than mangling the complete generic signature of a constrained
extension, only mangle the requirements not already satisfied by the
nominal type. For example, given:
extension Dictionary where Value: Equatable {
// OLD: _T0s10DictionaryV2t3s8HashableRzs9EquatableR_r0_lE3baryyF
// NEW: _T0s10DictionaryV2t3s9EquatableR_rlE3baryyF
public func bar() { }
}
In the existing mangling, we mangle the `Key: Hashable` requirement that’s
part of the generic signature. With this change, we only mangle the new
requirement (`Value: Equatable`).
This is a win for constrained extensions *except* in the case of a
constrained extension of a nominal type with a single, unconstrained
generic parameter:
extension Array where Element: Equatable {
// OLD: _T0Sa2t3s9EquatableRzlE3baryyF
// NEW would be: _T0Sa2t3s9EquatableRzrlE3baryyF
public func bar() { }
}
Check explicily for this shortcut mangling and fall back to the old
path, so this change is a strict improvement.
Use the "override" information in associated type declarations to provide
AST-level access to the associated type "anchor", i.e., the canonical
associated type that will be used in generic signatures, mangling,
etc.
In the Generic Signature Builder, only build potential archetypes for
associated types that are anchors, which reduces the number of
potential archetypes we build when type-checking the standard library
by 14% and type-checking time for the standard library by 16%.
There's a minor regression here in some generic signatures that were
accidentally getting (correct) same-type constraints. There were
existing bugs in this area already (Huon found some of them), while
will be addressed as a follow-up.
Fies SR-5726, where we were failing to type-check due to missed
associated type constraints.
The various _*Indexable protocols only exist to work around the lack of
recursive protocol constraints. Eliminate all of the *_Indexable protocols,
collapsing their requirements into the corresponding Collection protocol
(e.g., _MutableIndexable —> Collection).
This introduces a number of extraneous requirements into the various
Collection protocols to work around bugs in associated type
inference. Specifically, to work around the lack of "global" inference
of associated type witnesses. These hacks were implicitly present in
the *Indexable protocols; I've made marked them as ABI FIXMEs here so
we can remove them when associated type inference improves.
Fixes rdar://problem/21935030 and a number of ABI FIXMEs in the library.

The code goes into its own sub-tree under 'tools' but tests go under 'test',
so that running 'check-swift' will also run all the SourceKit tests.
SourceKit is disabled on non-darwin platforms.
