Argyrios Kyrtzidis 63aebfb4ae [objcmt] When in ARC mode, also convert "[[.. alloc] init]" messages to literals, 
since the change from +1 to +0 will be handled fine by ARC.

been declared on NSArray/NSDictionary.

Argyrios Kyrtzidis cebe722ef6 [objcmt] When using NSNumber numberWithInteger:/numberWithUnsignedInteger: be 
more liberal in rewriting when the parameter is an enum constant.

Argyrios Kyrtzidis 7bd957c12a [objcmt] Rewrite messages to NSString's stringWithUTF8String:/stringWithCString: 
to use the @() boxing syntax.

It will also rewrite uses of stringWithCString:encoding: where the encoding that is
used is NSASCIIStringEncoding or NSUTF8StringEncoding.

Argyrios Kyrtzidis 491e4aed31 [objcmt] Rewrite [NSNumber numberWith*] messages to the new @() boxing syntax. 
There are some caveats:
-If an implicit cast (e.g. int -> float for numberWithFloat:) was required, the message
 will not get rewritten
-If the message was with numberWithInteger:/numberWithUnsignedInteger:, which are very
 commonly used, be more liberal and allow the boxing syntax if the underlying type has
 same signedness and will not lose precision.

Argyrios Kyrtzidis c1dfed6572 [objcmt] When rewriting to array/dictionary literals, add an explicit

David Blaikie bbafb8a745 Unify naming of LangOptions variable/get function across the Clang stack (Lex to AST). 
The member variable is always "LangOpts" and the member function is always "getLangOpts".

Ted Kremenek f7639e1b4a Add new code migrator support for migrating existing Objective-C code to use 
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.

This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator.  We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.
