Summary: Initially, Scudo had a monolithic design where both C and C++ functions were living in the same library. This was not necessarily ideal, and with the work on -fsanitize=scudo, it became more apparent that this needed to change. We are splitting the new/delete interceptor in their own C++ library. This allows more flexibility, notably with regard to std::bad_alloc when the work is done. This also allows us to not link new & delete when using pure C. Additionally, we add the UBSan runtimes with Scudo, in order to be able to have a -fsanitize=scudo,undefined in Clang (see work in D39334). The changes in this patch: - split the cxx specific code in the scudo cmake file into a new library; (remove the spurious foreach loop, that was not necessary) - add the UBSan runtimes (both C and C++); - change the test cmake file to allow for specific C & C++ tests; - make C tests pure C, rename their extension accordingly.
