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.

Use this to remove the last bit of the hack to suppres noescape on setter
arguments. Add a more comprehensive test of noescape's interaction with
accessors.
That is, if you have this declaration:
struct Outer {
struct Inner {
// ...
}
}
and you're just printing 'Inner', print it like this:
struct Outer.Inner {
// ...
}
This comes up with the ClangImporter's import-as-member feature, and
is also about to affect how error code enums are imported as well.
This is currently only enabled in certain contexts: always when
printing interfaces, and for types (but not other members) when
printing declarations for Quick Help.

- Allow them to use substitutions.
- Consistently use 'a' as a mangling operator.
- For generic typealiases, include the alias as context for any generic
parameters.
Typealiases don't show up in symbol names, which always refer to
canonical types, but they are mangled for debug info and for USRs
(unique identifiers used by SourceKit), so it's good to get this
right.
Instead of appending a character for each substitution, we now prefix the substitution with the repeat count, e.g.
AbbbbB -> A5B
The same is done for known-type substitutions, e.g.
SiSiSi -> S3i
This significantly shrinks mangled names which contain large lists of the same type, like
func foo(_ x: (Int, Int, Int, Int, Int, Int, Int, Int, Int, Int, Int, Int))

cfe9e6a3de removed calls to pre/post
printing of PrintStructureKind::GenericRequirement, so SourceKit DocInfo
requests started droping the markers for generic requirements, causing
some weirdness with documentation rendering and post-processing.
Restore the calls to printStructPre/Post when printing generic
requirements.

Store leading a trailing "trivia" around a token, such as whitespace,
comments, doc comments, and escaping backticks. These are syntactically
important for preserving formatting when printing ASTs but don't
semantically affect the program.
Tokens take all trailing trivia up to, but not including, the next
newline. This is important to maintain checks that statements without
semicolon separators start on a new line, among other things.
Trivia are now data attached to the ends of tokens, not tokens
themselves.
Create a new Syntax sublibrary for upcoming immutable, persistent,
thread-safe ASTs, which will contain only the syntactic information
about source structure, as well as for generating new source code, and
structural editing. Proactively move swift::Token into there.
Since this patch is getting a bit large, a token fuzzer which checks
for round-trip equivlence with the workflow:
fuzzer => token stream => file1
=> Lexer => token stream => file 2 => diff(file1, file2)
Will arrive in a subsequent commit.
This patch does not change the grammar.
There was a ton of complicated logic here to work around
two problems:
- Same-type constraints were not represented properly in
RequirementReprs, requiring us to store them in strong form
and parse them out when printing type interfaces.
- The TypeBase::getAllGenericArgs() method did not do the
right thing for members of protocols and protocol extensions,
and so instead of simple calls to Type::subst(), we had
an elaborate 'ArchetypeTransformer' abstraction repeated
in two places.
Rewrite this code to use GenericSignatures and
GenericFunctionType instead of old-school GenericParamLists
and PolymorphicFunctionType.
This changes the code completion and AST printer output
slightly. A few of the changes are actually fixes for cases
where the old code didn't handle substitutions properly.
A few others are subjective, for example a generic parameter
list of the form <T : Proto> now prints as <T where T : Proto>.
We can add heuristics to make the output whatever we want
here; the important thing is that now we're using modern
abstractions.
and provide a fix-it to move it to the new location as referenced
in SE-0081.
Fix up a few stray places in the standard library that is still using
the old syntax.
Update any ./test files that aren't expecting the new warning/fix-it
in -verify mode.
While investigating what I thought was a new crash due to this new
diagnostic, I discovered two sources of quite a few compiler crashers
related to unterminated generic parameter lists, where the right
angle bracket source location was getting unconditionally set to
the current token, even though it wasn't actually a '>'.
Allow 'static' (or, in classes, final 'class') operators to be
declared within types and extensions thereof. Within protocols,
require operators to be marked 'static'. Use a warning with a Fix-It
to stage this in, so we don't break the world's code.
Protocol conformance checking already seems to work, so add some tests
for that. Update a pile of tests and the standard library to include
the required 'static' keywords.
There is an amusing name-mangling change here. Global operators were
getting marked as 'static' (for silly reasons), so their mangled names
had the 'Z' modifier for static methods, even though this doesn't make
sense. Now, operators within types and extensions need to be 'static'
as written.
Showing only the conforming associated types provides
little information to doc viewers. This patch digs the
underlying type of an associated type to report the
conformance info of those.
As a first foray into annotating attribute, add tags around attribute
names. For now, treat any decl-modifiers as keywords. We will also want
to wrap the whole attribute (including any parameters) into tags as
well, but that will require more work in the callback hanlding.
Also factor the attribute printing to handle any special cases early,
which will simplify wrapping attributes in tags, since we can then just
put the whole switch intside the pre/post callbacks.

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.

rdar://problem/24292304
Adds an associatedtype keyword to the parser tokens, and accepts either
typealias or associatedtype to create an AssociatedTypeDecl, warning
that the former is deprecated. The ASTPrinter now emits associatedtype
for AssociatedTypeDecls.
Separated AssociatedType from TypeAlias as two different kinds of
CodeCompletionDeclKinds. This part probably doesn’t turn out to be
absolutely necessary currently, but it is nice cleanup from formerly
specifically glomming the two together.
And then many, many changes to tests. The actual new tests for the fixits
is at the end of Generics/associated_types.swift.
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.
