Add support for optimized (non-generic) atomic libcalls. For integer types of sizes 1, 2, 4 and 8, libcompiler-rt (and libgcc) provide atomic functions that pass parameters by value and return results directly. libgcc and libcompiler-rt only provide optimized libcalls for __atomic_fetch_*, as generic libcalls on non-integer types would make little sense. This means that we can finally make __atomic_fetch_* work on architectures for which we don't provide these operations as builtins (e.g. ARM). This should fix the dreaded "cannot compile this atomic library call yet" error that would pop up once every while. llvm-svn: 183033
