Avoid upcoming GCC 9.0 warnings about base class init.
Currently, in trunk, GCC has a new warning under -Wextra
that diagnoses when a derived class fails to explicitly
initialize the base class in a constructor initializer list.
This patch avoids this warning.

absl: fix SpinLock::EncodeWaitCycles
If a thread has ever observed or set kSpinLockSleeper, it must
never leave 0 in kWaitTimeMask because at this point it is
expected to wake subsequent threads. Current calculations in
EncodeWaitCycles can result in 0 in kWaitTimeMask and lead to
missed wakeups. This is mostly theoretical today, because
the futex call needs to finish within 128 cycles (futex can
return immediately without waiting, but 128 cycles still
look too low for this). But this can well fire in future
if we bump granularity and/or threshold for recording contention.
Use kSpinLockSleeper instead of 0.

absl: optimize SpinLock::SlowLock
Currently we record contention even after the first initial spin.
This leads to several performance issues:
1. If we succeed in acquiring the lock after the initial spin,
overall wait time can be within tens/hundreds of nanoseconds.
Recording such low wait time looks completely unnecessary and excessive.
From some point of view this is not even a wait, because we did not sleep.
And, for example, Mutex does not record contention in this case.
In majority of cases the lock should be acquired exactly during the initial
spin, yet we still go through full overhead of submitting contention.
2. Whenever a thread submits contention it also calls FUTEX_WAKE
(there is no way to understand if it's necessary or not when wait value
is stored in the lock). So if there are just 2 threads and a brief
contention, the second thread will still call FUTEX_WAKE which
is completely unnecessary overhead.
Don't record contention after the initial spin wait.
FWIW this also removes 2 CycleClock::Now calls and EncodeWaitCycles
from the common hot path.

ba4dd47492748bd630462eb68b7959037fc6a11a by Abseil Team <absl-team@google.com>:
Work around nvcc 9.0 compiler bug for open-source Tensorflow build.
With the current implementation, when I (unintentionally and transitively)
include absl/types/optional.h in a CUDA compilation unit, I get the following
nvcc error message:
INFO: From Compiling tensorflow/core/kernels/crop_and_resize_op_gpu.cu.cc:
external/com_google_absl/absl/types/optional.h: In member function 'void absl::optional_internal::optional_data_dtor_base<T, <anonymous> >::destruct()':
external/com_google_absl/absl/types/optional.h:185:50: error: '__T0' was not declared in this scope
data_.~T();
I've also seen similar compilation failures online, for flat_hash_map:
https://devtalk.nvidia.com/default/topic/1042599/nvcc-preprocessor-bug-causes-compilation-failure/
The bug is always around unnamed template parameters. Therefore, the workaround is to make them named.
