Howard Hinnant 8b805c915a The rules for emplace in map, multimap, unordered_map and unordered_multimap changed a while back and I'm just now updating to these new rules. In a nutshell, you've got to know you're emplacing to a pair and use one of pair's constructors. I made one extension: If you want to emplace the key and default construct the mapped_type, you can just emplace(key), as opposed to emplace(piecewise_construct, forward_as_tuple(key), forward_as_tuple()).

Douglas Gregor 8f69b1af3d Move _LIBCPP_VISIBLE_INLINE from the out-of-line definitions of member 
functions to the original declarations, so that Clang will actually
see them. Part of <rdar://problem/11489333>.

Howard Hinnant 0ae9efeb1a 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.

Howard Hinnant bff1bfc6be 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.

Richard Smith 11ffde3d7e libc++: only #include <cxxabi.h> if it exists. This allows libc++ to build 
out of the box on Linux systems. If you're building against libc++abi, you
still need to make sure it can find <cxxabi.h> so it knows not to export
symbols which libc++abi provides.

Richard Smith 99f15d6eb7 libc++: Add some missing #includes to atomics tests. libc++ doesn't need these 
at the moment, but they allow these tests to be used to test clang against
libstdc++. Add myself to the credits file, as suggested by Howard.

Richard Smith 766e8ccbfc 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.

David Chisnall cd42f9446b 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.

David Chisnall 4fa71de024 Fix the remaining atomic tests, all of which were wrong for the case where a 
compare-and-exchange failed (it should update the expected value to the current
value, and the tests were checking that it didn't...).

Results of the atomics part of the test suite on FreeBSD with clang trunk and
the atomic.c from compiler-rt (currently kludged into the test, not installed
properly):

Howard Hinnant 7e5b4c9328 Put std::piecewise_construct_t back into the dylib for ABI stability. When clients are in C++11/constexpr mode this will be safely ignored because piecewise_construct is then declared with internal linkage.

Howard Hinnant 788c9979d9 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.

Howard Hinnant 0527c6207a 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.

Howard Hinnant cb16c68042 It appears that the standard accidentally removed the default constructor for error_category. I'm putting it back in. This fixes http://llvm.org/bugs/show_bug.cgi?id=12321.

Howard Hinnant b2f52bb982 Allow libc++ to be built with CMake from within the LLVM tree. The libc++ part is just some renaming as the variable was already in use, conflicting with something else in the LLVM tree. Contributed by Ruben Van Boxem.

Howard Hinnant 27e618efb6 I'm reverting one of the changes made to exception.cpp in r151717. I'm unsure what the change was trying to do, but it didn't do the right thing for __APPLE__. So instead of trying to guess what was intended, I'm just putting it back the way it was.

David Chisnall 14c25b80e9 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.
