Mark all member functions with memory models always inline v2
When a non constant memory model is passed to __atomic_*
gcc falls back to seq_cst. This drops any HLE acquire or release bits.
This can happen when <atomic> is used with -O0
as the member functions are not always inlined then and the memory
argument passed in ends up being non-constant.
