attributes in more places where we didn't and catching a lot more issues.
This implements nearly every aspect of C++11 attribute parsing, except for:
- Attributes are permitted on explicit instantiations inside the declarator
(but not preceding the decl-spec)
- Attributes are permitted on friend declarations of functions.
- Multiple instances of the same attribute in an attribute-list (e.g.
[[noreturn, noreturn]], not [[noreturn]] [[noreturn]] which is conforming)
are allowed.
The first two are marked as expected-FIXME in the test file and the latter
is probably a defect and is currently untested.
Thanks to Richard Smith for providing the lion's share of the testcases.

such as "protocol" and "expression" being implicitly turned into links to
mistakenly-generated Doxygen pages:
- Escaping @ symbols when Doxygen would otherwise incorrectly interpret them;
- Escaping # symbols when they're not intended as explicit Doxygen link
requests, such as when discussing preprocessor directives;
- In one odd case, unescaping @ in @__experimental_modules_import, because
Doxygen wrote '\@' to the output in that case, causing the example in the
description of ImportDecl to be wrong; and
- Fixing a typo: @breif -> @brief.

NSNumber, and boolean literals. This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.
My apologies for the large patch. It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.
Docs are forthcoming to document the implementation and behavior of these features.

grammar requires a string-literal and not a user-defined-string-literal. The
two constructs are still represented by the same TokenKind, in order to prevent
a combinatorial explosion of different kinds of token. A flag on Token tracks
whether a ud-suffix is present, in order to prevent clients from needing to look
at the token's spelling.

statement is compound statement or next statement has more
indentation.
Replacing the semicolon with {} or moving the semicolon to the next
line will always silence the warning.

Parsing of @implementations was based on modifying global state from
the parser; the logic for late parsing of methods was spread in multiple places
making it difficult to have a robust error recovery.
-it was difficult to ensure that we don't neglect parsing the lexed methods.
-it was difficult to setup the original objc container context for parsing the lexed methods
after completing ParseObjCAtImplementationDeclaration and returning to top level context.
Enhance parsing of @implementations by centralizing it in Parser::ParseObjCAtImplementationDeclaration().
ParseObjCAtImplementationDeclaration now returns only after an @implementation is fully parsed;
all the data and logic for late parsing of methods is now in one place.
This allows us to provide code-completion for late parsed methods with mis-matched braces.

Stopping at '@' was originally intended to avoid skipping an '@' at the @interface context
when doing parser recovery, but we should not stop at all '@' tokens because they may be part
of expressions (e.g. in @"string", @selector(), etc.), so in most cases we will want to skip them.
This commit caused 'test/Parser/method-def-in-class.m' to fail for the cases where we tried to
recover from unmatched angle bracket but IMO it is not a big deal to not have good recovery
from such broken code and the way we did recovery would not always work anyway (e.g. if there was '@'
in an expression).
The case that rdar://7029784 is about still passes.

because the memory associated with them is going to get released.
We also don't want them to affect later parsing.
(We do the same for C++ inline methods.)
The underlying cause for the leftover tokens is going to be addressed in the
next commit.

'id' that can be used (only!) via a contextual keyword as the result
type of an Objective-C message send. 'instancetype' then gives the

Previously we would cut off the source file buffer at the code-completion
point; this impeded code-completion inside C++ inline methods and,
recently, with buffering ObjC methods.
Have the code-completion inserted into the source buffer so that it can
be buffered along with a method body. When we actually hit the code-completion
point the cut-off lexing or parsing.

Related result types apply Cocoa conventions to the type of message
sends and property accesses to Objective-C methods that are known to
always return objects whose type is the same as the type of the
receiving class (or a subclass thereof), such as +alloc and
-init. This tightens up static type safety for Objective-C, so that we
now diagnose mistakes like this:
t.m:4:10: warning: incompatible pointer types initializing 'NSSet *'
with an
expression of type 'NSArray *' [-Wincompatible-pointer-types]
NSSet *array = [[NSArray alloc] init];
^ ~~~~~~~~~~~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1:
note:
instance method 'init' is assumed to return an instance of its
receiver
type ('NSArray *')
- (id)init;
^
It also means that we get decent type inference when writing code in
Objective-C++0x:
auto array = [[NSMutableArray alloc] initWithObjects:@"one", @"two",nil];
// ^ now infers NSMutableArray* rather than id

classes, categories, protocols, and class extensions, where the
methods and properties of these entities would be inserted into the
DeclContext in an ordering that doesn't necessarily reflect source
order. The culprits were Sema::ActOnMethodDeclaration(), which did not
perform the insertion of the just-created method declaration into
the DeclContext for these Objective-C entities, and
Sema::ActOnAtEnd(), which inserted all method declarations at the
*end* of the DeclContext.
With this fix in hand, clean up the code-completion actions for
property setters/getters that worked around this brokenness in the AST.
Fixes <rdar://problem/8062781>, where this problem manifested as poor
token-annotation information, but this would have struck again in many
other places.
