Summary:
`Better` is a trivial collection of basic tools borrowed from other low-level general purpose libraries (like Folly, Abseil or Boost). The main goals of Better:
- Make the codebase more portable;
- Make the dependency list explicit (by decoupling it as a dependency list of Better);
- Make relying on modern C++ patterns and tools in code simple and easy.
- Make executing experiments with different dependencies easier.
As a first example usage, this diff replaces std::unordered_map with an efficient one from folly on the one of the hottest paths.

Summary:
ShadowView, ShadowViewMutation, and Differentiator were decoupled to separate module.
That enables us to use ShadowView more widely without facing a circular dependency problem.
