Alex Stewart df6e27e13b Fix calculation of Solver::Summary::num_threads_used. 
- 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.

Alex Stewart d856af0859 Add no-threads ParallelFor implementation. 
- When Ceres was configured without any multithreading enabled (actually
  the default) it would fail to build due to undefined symbols for
  ParallelFor() as there was no implementation for that case.
- This adds a trivial single-threaded implementation for that case,
  taken from the C++11 threads implementation.
