Also, we always print accessibility keywords in the printed interfaces, so that users can differentiate public and
internal decls.

We improve the efficiency through two ways: 1. read the protocol keywords, such as
http, radar, or im, to select the right regex pattern to search for instead of
trying every known patterns; and 2. reduce the regex search space by truncating
text before protocol keywords. rdar://21009781

Adding the following to a doc comment:
- throws: ...
Will create a description about what/when the function will throw.
This should be a peer to "- returns:" and "- parameter:" and not appear
inline in the description.

First, fix a case of type checking an expression twice, which is against
the design of the type checker. We hit this because we can type check
the "context" in
let x = foo.#^COMPLETE^#
and then type check the "parsed expression", which is contained in the
context here.
Second, make the hack from rdar://20738314 more robust so that if we
*do* double typecheck for some reason we won't just choke on an
AutoClosureExpr. I filed rdar://21466394 to audit for other cases of
double typechecking and remove this hack.

Doc comments assume a prefix of /** and a suffix of */
but if a user accidentally types /**/, SourceKit can crash and
bring down Xcode with certain timings. Check both ends of doc
comments before dropping characters.

This returns to the behaviour we had before ModuleDecl came about. It
fixes an assertion in SourceKit concerning the kinds of decls we will
visit in visitDeclReference. As the comments indicate, we need this
special case until Swift supports first class submodules.

- Start highlighting doc comments as Xcode "Documentation Comments".
- Start highlighting custom top-level fields as Xcode "Documentation
Comment Keywords".
This requires SourceKit r28827 to build and Xcode

Completions for calling functions will now show 'throws' in the
description text so that users can differentiate throwing and
non-throwing calls. We don't insert this into the source text, since
it's not part of the call syntax.

declarations generated by the type-checker.
Unfortunately, it's not possible to directly check this
because the verifier is itself based on ASTWalker. But I'm
going to add an assertion to SILGen in a follow-up that
assumes that TypeCheckError has visited every ApplyExpr,
and since SILGen already walks most of the AST with its
own custom walker, that will check this well enough.

It's not okay to filter to only ErrorType results, since we may be
trying to chain to an error type result foo.bar.getError(). And the
existing logic had no way to handle results from other modules, so we
were missing key results like 'NSError'.
Eventually we'll want to bring back something like this that handles all
modules, but as a way to bump the priority of ErrorType results rather
than to filter out everything else.

protocol P { typealias T; func foo() -> T }
func invalid(x: P) { x.#^COMPLETE^#
We were trying to access a null Type created because the associated type
doesn't make sense in the protocol type P (we can only use P as a
generic constraint, but it shouldn't crash code completion if we use it
incorrectly).
For rdar://problem/20305938
Swift SVN r28588
We were asserting (and doing the wrong thing) when trying to code
complete
nil #^HERE^#
The issue is that we tried to apply a solution to the expression that
contained free type variables (converted to generic parameters). This
trips us up when we expect the new type to conform to protocols. In code
completion we generally only need the type of the expression, so this
commit switches to getting that more explicitly. That said, this did
cause us to drop non-API parameter names in call patterns after an
opening '(' in some cases (covered by rdar://20962472).
Thanks to Doug for suggesting this solution!

instead of being an expression.
To the user, this has a couple of behavior changes, stemming from its non-expression-likeness.
- #available cannot be parenthesized anymore
- #available is in its own clause, not used in a 'where' clause of if/let.
Also, the implementation in the compiler is simpler and fits the model better. This
fixes:
<rdar://problem/20904820> Following a "let" condition with #available is incorrectly rejected
Swift SVN r28521
This came out of today's language review meeting.
The intent is to match #available with the attribute
that describes availability.
This is a divergence from Objective-C.
Swift SVN r28484
Now that we don't have generic parameter lists at arbitrary positions
within the extended type of an extension declaration, simplify the
representation of the extended type down to a TypeLoc along with a
(compiler-synthesized) generic parameter list.
On the parsing side, just parse a type for the extended type, rather
than having a special grammar. We still reject anything that is not a
nominal type (of course), but it's simpler just to call it a type.
As a drive-by, fix the crasher when extending a type with module
qualification, rdar://problem/20900870.

When we miss the in-memory (libcache-based) code completion cache, we
can now chain to an on-disk code completion cache. This drastically
improves the time and peak memory usage it takes to do the first code
completion (ie. before the in-memory cache is warm) if we've done the
same lookup before.
The on-disk cache, like the in-memory cache is tied to the specific
compiled swift and clang module files (.swiftmodule and .pcm), and will
consider itself out of date if they are modified. Responsibility for
deleting completely dead/unreachable cache files falls to the client.
Most of this commit is adding a simple serialization and deserialization
for CodeCompletionResults and CodeCompletionStrings. The format is very
simple, using an array of fixed size CodeCompletionResults, with offsets
into two blobs: one for CodeCompletionString::Chunks, and one for
strings. Currently that gives us about 5.8 MB for all the results in
Cocoa, but it's very compressible if we decide we want to reduce it
(gzip'd it is ~1.2 MB for the same data).
Swift SVN r28369
This will let us implement caching in the client (e.g. SourceKit) at
some point and simplifies adding more levels of caching. Requires a
corresponding SourceKit change.
Swift SVN r28365
Instead of importing everything and filtering later (so all of clang modules get deserialized and associated Swift decls get created),
lazily import as Swift decls only the Clang decls that we need from a particular header.
This also fixes printing ObjC categories in the header as Swift extensions.
Swift SVN r28358
Make unqualified lookup always provide a declaration for the things it
finds, rather than providing either a module or a declaration. Unify
various code paths in our type checker now that module declarations
come in with the other declarations.
