Evaluate Fasttrack2 algorithm for race-detection

[fmoessbauer]

As stated in #11, using TSAN imposes multiple limitations and technical issues on the detection backend. This is mainly due to the direct-address mapping strategy, implemented in TSAN.

In the thesis, I proposed to also evaluate other race-detection backends like Fasttrack2. This was not possible due to the limited time, as well as due to the focus on the instrumentation part.
However, DRace is already prepared for this scenario as the detector is connected using a generic interface.

For Fasttrack2, there currently exists only an OSS implementation for Java, which would have to be ported to C++.
Fortunately this code is well documented and the logic behind is described in this paper, so a port should not be too time consuming.
