Boxed Expressions

I added a new section to the Objective-C literals document:

http://clang.llvm.org/docs/ObjectiveCLiterals.html#objc_boxed_expressions

This describes the syntax we are implementing for boxed expressions. This lets you write code like:

// numbers.
NSNumber *smallestInt = @(-INT_MAX - 1);
NSNumber *piOverTwo = @(M_PI / 2);
// enumerated types.
typedef enum { Red, Green, Blue } Color;
NSNumber *favoriteColor = @(Green);

// strings.
NSString *path = @(getenv("PATH"));
NSArray *pathComponents = [path componentsSeparatedByString:@":"];
