The new test in LSTMTrainer::UpdateErrorGraph fixes an assertion
(see issues #644, #792).
The new test in LSTMTrainer::ReadTrainingDump was added to improve
the robustness of the code.

The code in ccutil/hashfn.h was needed for some old compilers. Now that we support MSVC >= 2010 and compilers that has good support for C++11, we can drop this code.
As a result of this file removal, we now use:
std::unordered_map
std::unordered_set
std::unique_ptr
directly in the codebase with '#include' for the needed headers.
