Douglas Gregor 813a066f16 Extend type nullability qualifiers for Objective-C. 
Introduce context-sensitive, non-underscored nullability specifiers
(nonnull, nullable, null_unspecified) for Objective-C method return
types, method parameter types, and properties.

Introduce Objective-C-specific semantics, including computation of the
nullability of the result of a message send, merging of nullability
information from the @interface of a class into its @implementation,
etc .

This is the Objective-C part of rdar://problem/18868820.

Manuel Klimek 2acb7b7bb1 Fix single-line optimization for ObjC. 
Puts blocks always into multiple lines when they start with an ObjC
keyword or minus.

Manuel Klimek f4ab9ef34c Implements pulling simple blocks into a single line. 
void f() { return 42; }

The final change that implements the feature.

Nico Weber a608775ba2 Formatting: In @implementation etc lines, put a space before protocol lists. 
Don't do this in Google style though:
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Protocols

Most other places (function declarations, variable declarations) still get
this wrong, and since this looks very similiar to template instantiations to
the lexer (`id <MyProtocol> a = ...`), it's going to be hard to fix in some
places.

Nico Weber 2bb0074232 Formatter: Add space before '(' in @implemenation, @interface, @protocol lines 
The first token in @implementation, @interface, and @protocol lines is now
marked TT_ObjCDecl, and lines starting with a TT_ObjCDecl token are now marked
LT_ObjCMethodDecl.

Nico Weber 51306d232e Formatter: @optional and @required go on their own line. 
Previously:
@protocol myProtocol
- (void)mandatoryWithInt:(int)i;
@optional - (void) optional;
@required - (void) required;
@end

Now:
@protocol myProtocol
- (void)mandatoryWithInt:(int)i;
@optional
- (void)optional;
@required
- (void)required;
@end

Nico Weber 2ce0ac5a8c Formatter: Add support for @implementation. 
Just reuse the @interface code for this. It accepts slightly more than
necessary (@implementation cannot have protocol lists), but that's ok.

Nico Weber 4d03055e70 Fix test after r171995. 
I wasn't aware libFormat is used elsewhere already. Let me know if rebasing
is not the right thing to do here.

Manuel Klimek 1abf789c7a Various fixes to clang-format's macro handling. 
Some of this is still pretty rough (note the load of FIXMEs), but it is
strictly an improvement and fixes various bugs that were related to
macro processing but are also imporant in non-macro use cases.

Specific fixes:
- correctly puts espaced newlines at the end of the line
- fixes counting of white space before a token when escaped newlines are
  present
- fixes parsing of "trailing" tokens when eof() is hit
- puts macro parsing orthogonal to parsing other structure
- general support for parsing of macro definitions

Due to the fix to format trailing tokens, this change also includes a
bunch of fixes to the c-index tests.

Fariborz Jahanian 68a542aea7 Add objective-C style formatting to clang format and 
use it to format xml declaration tags.

Fariborz Jahanian 9b7ab87738 This is the libclang patch providing minimal API to 
use clang's formatter. Currently, formatter is used 
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.
