96b030a8e4 Re-enable FMA for fast sqrt functions 
This commit re-enables the use of FMA for the FAST sqrt functions.
Doing so improves the performance of both algorithms.  The float32
version is now 88% the speed of the original function, while the
double version is 90%.

705f66a9ca Account for missing change on commit "Remove SimpleThreadPool and..." 
"... always use {NonBlocking}ThreadPool". It seems the non-blocking
implementation was me the default/only one, but a reference to the old
name was left unmodified. Fix that.

02eaaacbc5 Move cxx11_tensor_uint128 test under an EIGEN_TEST_CXX11 guarded 
block

Builds configured without the -DEIGEN_TEST_CXX11=ON flag would fail
right away without this, as this test seems to rely on those language
features. The skip under compilation with MSVC was kept.

c58b874727 PR430: Convert count to the reducer type in MeanReducer 
Without explicit conversion Tensorflow fails to compile, pset1 template deduction fails.

cannot convert '((const Eigen::internal::MeanReducer<Eigen::half>*)this)
  ->Eigen::internal::MeanReducer<Eigen::half>::packetCount_'
(type 'const DenseIndex {aka const long int}')
to type 'const type& {aka const Eigen::half&}'
     return pdiv(vaccum, pset1<Packet>(packetCount_));
Honestly I’m not sure why it works in Eigen tests, because Eigen::half constructor is explicit, and why it stopped working in TF, I didn’t find any relevant changes since previous Eigen upgrade.

static_cast<T>(packetCount_) - breaks cxx11_tensor_reductions test for Eigen::half, also quite surprising.
