5b0186dc7d Added implementation of 64-bit atomic operations on 32-bit Windows. Pointer specializations of 64-bit CAS-based atomic implementation extracted to a separate header, since these specializations are not needed on 32-bit platforms.

f9c4249c8e 1. Fixed compilation with MSVC 2003. 
2. Fixed incorrect reinterpret_casts in constexpr constructors that could result in buffer overruns. The initializing constructors for non-integral atomics are not constexpr yet because memcpy must be used inside.
3. Made atomic_flag default constructors constexpr. This is not by the standard but we do not implement ATOMIC_FLAG_INIT yet, so the default constructor is needed and it should be constexpr when possible.
4. Fixed a few syntax errors and cleaned up the code a bit.
5. Moved operator value_type() to the interface class in order not to duplicate it in base_atomic specializations.
6. The return type of operator=() changed to follow the standard.

3c288331b0 atomic: make use of gcc's __GCC_HAVE_SYNC_COMPARE_AND_SWAP_8

around this, we provide a separate implementation via gcc's atomic builtins

3870d2bf30 Catch conflicting macro definitions 
Compilation reportedly fails on icc, conflicting macro definitions (both
__i686__ and __x86_64__ defined) is under suspicion. This patch tentatively
fixes the issue.
