Hinted lock (OpenMP 4.5 feature) Updates/Fixes
There are going to be two more patches which bring this feature up to date and in line with OpenMP 4.5.
- Renamed jump tables for the lock functions (and some clean up).
- Renamed some macros to be in KMP_ namespace.
- Return type of unset functions changed from void to int.
- Enabled use of _xebgin() et al. intrinsics for accessing TSX instructions.
