* Headers/Foundation/NSMethodSignature.h

Browse source 
(_internalMethodTypes): New instance variable.
        * Source/NSMethodSignature.m: ([+signatureWithObjCTypes]): Store
        the runtime signature separately from the mframe signature.
        Document.
        ([-dealloc]): Free new instance variable.
        ([-methodInfo]): Use _internalMethodTypes to build argument
        information.

        * Source/GSFFCallInvocation.m (GSInvocationCallback)
        * Source/GSFFIInvocation.m (GSInvocationCallback): Use the
        selector registered in the runtime for the receiver instead of
        the constructed selector from the stack to avoid mismatches in the
        runtime.
