Fix jitbench

Fix jitbench

Addressed 3 issues:
1) coreclr and CoreFx were out of sync -> update dependencies.props
2) Word2Vec fails on x86 sometimes with OutOfMemory -> disabled it there because it appears the behavior is by design
3) CommandLineParser 2.1.1 doesn't restore anymore? -> NuGet was already rolling forward to 2.2.0 but changing it in the source removes the warning when using dotnet.exe to run JitBench
