// Thread local support required for UnwindImpl.
// Notes:
// * Xcode's clang did not support `thread_local` until version 8, and
// even then not for all iOS < 9.0.
// * Xcode 9.3 started disallowing `thread_local` for 32-bit iOS simulator
// targeting iOS 9.x.
// * Xcode 10 moves the deployment target check for iOS < 9.0 to link time
// making __has_feature unreliable there.
//
// Otherwise, `__has_feature` is only supported by Clang so it has be inside
// `defined(__APPLE__)` check.
