This first MR create an internal structured representation of the CFG and computes the domination relationship. Over a few other MRs I will implement an algorithm inspired to [this article](https://medium.com/leaningtech/solving-the-structured-control-flow… to compute a better structure than the one we already have, but for the moment the computed data is immediately wasted. A working prototype of the new structurizer is now available in https://gitlab.winehq.org/giomasce/vkd3d/-/commits/cfg4, though further improvement is planned on top of that too.

Implements asin, acos, atan, and atan2.
Also includes some tests in a new test file.
One possible problem here is that I'm not sure how to test what Microsoft's atan and atan2 outputs are in boundary cases like atan2(1, 0). I've made the test suites adhere with the calculator program I've been using (Qalculate, which I assume is using libc's atan2).
