Signed flag is now forwarded to the backends.
...
Forwarding the "signed" property allows to specialize operations
implementation, which may be desired for some architectures. This also
eliminates the formally implementation-defined result of unsigned-to-
target type.
Also for x86 implementations removed compiler barriers since the
compilers already treat intrinsics/asm blocks as ones.

Added a generic atomic<> implementation based on the new __atomic intrinsics available in gcc 4.7 and clang 3.2. The new implementation adds support for 128-bit atomic. Other implementations updated to employ new macros in Boost.Config for defaulted and deleted functions (this is not complete yet). Fixed padding for the lock pool. Initializing constructor for atomic<> made explicit to avoid ambiguities of different overloads of operator=.
