[LLVMdev] StructType for dispatch_object_t changed by Linker

Duncan, thanks for your reply.

In the module loaded in Step 1 (otherModule): 

%struct.dispatch_group_s = type opaque
%union.dispatch_object_t = type { %struct.dispatch_object_s* }
%struct.dispatch_object_s = type opaque

In the module generated in Step 2 (mainModule): 

%struct.dispatch_group_s = type {}
%union.dispatch_object_t = type { %struct.dispatch_object_s* }
%struct.dispatch_object_s = type {}

(The LLVM API calls to generate mainModule were generated by calling `llc -march=cpp` on otherModule.)

Great, I'll also test on 3.2 when I get a chance. Thanks.
