The C++20 Coroutines couldn't be compiled to WebAssembly due to an optimization named symmetric transfer requires the support for musttail calls but WebAssembly doesn't support it yet. So the revision tried to disable the optimization for WebAssembly to make we could compile standard C++20 codes in that platform.
