Implement Objective-C Related Result Type semantics.
...
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

Implement caching of copy assignment operator lookup.
...
I believe, upon, careful review, that this code causes us to incorrectly
handle exception specifications of copy assignment operators in C++03
mode. However, we currently do not seem to properly implement the subtle
distinction between copying of members and bases made by implicit copy
constructors and assignment operators in C++03 - namely that they are
limited in their overload selection - in all cases. As such, I feel that
committing this code is correct pending a careful review of our
implementation of these semantics.
