Oscar Fuentes 8b6d88d2f8 Fixes the Atomic implementation if compiled by MSVC compiler. 
sys::cas_flag should be long on this platform, InterlockedAdd() is
defined only for the Itanium architecture (according to MSDN).

Patch by Michael Beck!

Owen Anderson 5cc4131063 Revert my last series of commits related to Timer and 64-bit atomics. Not all the targets 
we care about are capable of supporting it.

Owen Anderson 9e3df5b67f Label the existing atomic functions as 32-bit specific, and add a 64-bit one that will be useful in 
the near future.

Owen Anderson 8d0fe6f0d7 Add an atomic increment and decrement implementation, which will be used for 
thread-safe reference counting.

Owen Anderson 5b9400d6bd I just fail today. 
Hopefully this fixes the last build errors on systems with GCC < 4.1.

Owen Anderson e5370f409b Move atomic operations' definitions out of line. While this seems kind of silly, 
all kinds of problems caused by including windows.h and/or config.h in an LLVM header.
