SFINAE __bit_iterator such that it will only get instantiated with a container that has the nested type __storage_type. This prevents accidental instantiation such as in http://llvm.org/bugs/show_bug.cgi?id=12755 . This fixes http://llvm.org/bugs/show_bug.cgi?id=12755 .

I believe tuple is still under development in the standard. Daniel Krugler is/will be making convincing arguments that a modified form of LWG 2051 (currently NAD Future) is easily acheivable and desirable. He has demonstrated that a tuple<T...> where all of the T are implicitly convertible from U... should have a tuple constructor that is also implicit, instead of explicit. This would support the use cases in LWG 2051 while not undermining T... with explicit conversions from U.... This check-in is an experimental implementation of Daniel's work. I believe this work to be mature enough to warrant inclusion into libc++. If anyone sees real-world problems that this check in causes, please let me know and I will revert it, and provide the feedback to the LWG.
