74f4da7219 Stephan Tolksdorf: fixes the issue in the <atomic> header and adds corresponding tests. I've used macros to fall back to a user-provided default constructor if _LIBCPP_HAS_NO_DEFAULTED_FUNCTIONS (though I suspect that there won't be many users defining that macro).
The tests use placement new to check that atomic values get properly zero-initialized. I had to modify the atomic_is_lock_free test, because default initialization of an object of const type 'const A' (aka 'const atomic<int>') requires a user-provided default constructor.

6ae47055f9 atomic_bool was missing (just a typedef to atomic<bool>).

9efdc0bd5f 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.

d3eca759a2 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):

1ee87fa41a Fix test cases that were trying to make atomic things that are not trivially copyable.
Now all of the test cases compile.  Some of them even run!

770d1c4ea7 After a long break to wait for the atomic spec to settle, this completes the library part of <atomic>. It currently won't even parse as it depends on the existence of the intrinsics specified at http://libcxx.llvm.org/atomic_design_a.html. Everything has been tested using fake intrinsics which have now been removed. As the intrinsics come online, the ATOMIC_* macros will need to be adjusted to reflect which operations are lock-free. These macros will probably need to be #ifdef'd for each supported platform.

4777bf2799 Getting <atomic> warmed back up. We have a hopefully more stable spec now. And I believe the intrinsic spec at http://libcxx.llvm.org/atomic_design_a.html is still good.

611fdaf229 Still working on the basic design of <atomic>. I'm working towards a system by which the compiler only needs to define the strongest intrinsics it can. Weaker atomics in the library automatically try stronger and stronger variants, picking the weakest compiler intrinsic available. If no compiler intrinsics are available for a given operation, the library locks a mutex and does the job. Better documentation to follow...
