Use placement new and delete with Waiter objects. PiperOrigin-RevId: 277728823 -- 1ba6edf421dd2dfe13c55970a03c99592cb6677d by Derek Mauro <dmauro@google.com>: Use lowercase spelling for include of dbghelp.h When cross-compiling under MinGW this is important PiperOrigin-RevId: 277629783 -- cfc662a6fa357a84ddda8037156c7f26cee40c36 by Abseil Team <absl-team@google.com>: Don't use atomic ops on waiter and wakeup counts in WIN32 waiter mode. Port the new CONDVAR waiter mode code in CL 277366017 to the WIN32 waiter mode.
