Fix atomicread/write operations
In `libraries/ghc-prim/cbits/atomic.c` no barriers were issued for
atomic read and write operations. Starting with gcc 4.7 compiler
intrinsics are offered. The atomic intrinisics are also available in
clang. Use these to implement `hs_atomicread*` and `hs_atomicwrite`.
Test Plan: validate on OSX and Windows
