f6fbb03bff276e72123e8590519079e87732ae62 by Abseil Team <absl-team@google.com>:
Replace static absl::Mutex with SpinLock in absl::Cords
to avoid static initializers by absl::Mutex destructors

654b7d9edfdc24f226990b2b46cbf91451a1d92a by Martijn Vels <mvels@google.com>:
Implement global data for CordzInfo in an ODR hardened way
This change puts the global data into a global list structure, and stores a reference to the global list in the handle itself. This hardens the implementation against ODR violations where info pointers are crossing dynamic library boundaries which are privately loaded.

e555985eabe63fcf0e980e9c433dd84caffec191 by Martijn Vels <mvels@google.com>:
Add MaybeUntrackCord() function
This function is near identical to the old UntrackCord() but allows info to be null, moving the cord.is_profiled() branch into CordzInfo.
