This reverts commit cd3091a88f7c55c90d9b5fff372ce1cdfc71948d. This change crashes on macOS systems in formatters::StdlibCoroutineHandleSyntheticFrontEnd when it fails to create the `ValueObjectSP promise` and calls a method on it. The failure causes a segfault while running TestCoroutineHandle.py on the "LLDB Incremental" CI bot, https://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake/ This change originally landed via https://reviews.llvm.org/D132815
