[PATCH] [OPENMP] CodeGen for "omp atomic read [seq_cst]" directive.

[Bataev, Alexey]

I discussed this problem with the author of atomics in OpenMP already. I 
hope to get the answer from him tomorrow.
PS. I'll try to investigate this problem a little bit more, maybe I'll 
come into some suitable solution. I have an idea in mind, but I need to 
play with it a little bit.
PPS. gcc uses global lock for all atomic operations and that's all. In 
icc there is a little bit more complex solution. I want to use an 
existing infrastructure of clang/LLVM.

Best regards,
Alexey Bataev
