- Previously we were only bounding num_threads_used based on whether
CERES_NO_THREADS was defined, meaning that we could erroneously report
a value larger than the number of threads actually used.

This is in preparation for adding support for a C++11 based parallel
for implementation. The code is behind CERES_USE_CXX11_THREADS which
is not exposed to the user yet.
Tested by building with and without CERES_USE_CXX11_THREADS defined
and the tests pass.
