1a32bcb4 - [lldb] Allow building using Mingw-w64 on Windows. (#150398)

[lldb] Allow building using Mingw-w64 on Windows. (#150398) I wasn't able to build lldb using Mingw-w64 on Windows without changing these 3 lines. It seems like `std::atomic<bool>` wasn't being found without `#include <atomic>` and `ceil` was defaulting to `std::ceil` instead of `std::chrono::ceil`, but I'm not smart enough to know the root cause. I'm sure I'm not the first people to try and compile lldb (and clang and lld) with Mingw-w64 and I don't know if something is wrong with my Mingw-w64, but my changes shouldn't have any affect if they aren't needed.
