Chuanqi Xu 2fbd254aa4 [Coroutines] [Clang] Look up coroutine component in std namespace first ... Summary: Now in libcxx and clang, all the coroutine components are defined in std::experimental namespace. And now the coroutine TS is merged into C++20. So in the working draft like N4892, we could find the coroutine components is defined in std namespace instead of std::experimental namespace. And the coroutine support in clang seems to be relatively stable. So I think it may be suitable to move the coroutine component into the experiment namespace now. But move the coroutine component into the std namespace may be an break change. So I planned to split this change into two patch. One in clang and other in libcxx. This patch would make clang lookup coroutine_traits in std namespace first. For the compatibility consideration, clang would lookup in std::experimental namespace if it can't find definitions in std namespace and emit a warning in this case. So the existing codes wouldn't be break after update compiler.
