Classification:Other Bug Reproducible:Always
 
Summary:
When calling a method that is also the declared getter for a property, the unused-getter-return-value warning is given when the return value of that method call are unused.

Steps to Reproduce:

@interface Model
@property (nonatomic, readonly, getter=getOrCreateGroup) id group;
@end
@implementation Model {
    id _group;
}
- (void)method {
    [self getOrCreateGroup];
}
- (id)getOrCreateGroup {
    if (!_group) {
        _group = @"group"; // Perform potentially mutating method
    }
    return _group;
}
@end

Expected Results:
There should be no warning on `[self getOrCreateGroup]` since it is a method call, not accessing the property through dot syntax.

Actual Results:
An unused-getter-return-value warning is given.

Regression:
This warning is not given in Xcode 6.2 Beta and before, is given in 6.3 Beta 1.
