87073e4bfb Greatly scale back ambitions of emulating move semantics in C++03 mode. It was causing more problems than it solved. This fixes http://llvm.org/bugs/show_bug.cgi?id=12704.

6186c7fe6a Switch libc++ from __atomic_* builtins to __c11_atomic_* builtins.
Per discussion with Howard, we are not interested in maintaining
compatibility with older versions of clang.

All tests pass with ToT clang, except for two which assert due to
a pre-existing, unrelated bug.

b2292091cb Now that clang supports doing the right thing with regard to atomic
initialisation, do the right thing with regard to atomic initialisation.

Note: clang r154507 or later required for <atomic> to work now.

27b4fd30ef This is an initial commit of constexpr support as proposed by Richard Smith. This by no means completes constexpr support. Indeed, it hardly scratches the surface. All it does is lay the foundation in <__config> and changes those few places in the library that are already using that foundation.

dc1345fd44 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.

997e454139 Solaris port. Currently sees around 200 test failures, mostly related to
Solaris not providing some of the locales that the test suite uses.

Note: This depends on an xlocale (partial) implementation for Solaris and a
couple of fixed standard headers.  These will be committed to a branch later
today.

Add constraints to some shared_ptr and weak_ptr constructors and assignment operators so that is_constructible/is_assignable give the correct answers for shared_ptr and weak_ptr. 6. Make defensive preparations in the shared_ptr free functions for the introduction of shared_ptr<T[]> in the future. 7. As an optimization, add move constructor and move assignment to weak_ptr.

cf2654bae7 Version #next on the hash functions for scalars. This builds on Dave's work, extends it to T*, and changes the way double and long double are handled (no longer convert to float on 32 bit). I also picked up a minor bug with uninitialized bits on the upper end of size_t when sizeof(size_t) > sizeof(T), e.g. in hash<float>. Most of the functionality has been put in one place: __scalar_hash in <memory>. Unfortunately I could not reuse __scalar_hash for hash<long double> on x86 because of the padding bits which need to be zeroed. I didn't want to add this zeroing step to the more general __scalar_hash when it isn't needed (in the absence of padding bits). I'm not ignoring the hash<string> issue (possibly changing that to a better hash). I just haven't gotten there yet.
