Kostya Kortchinsky d937b0a10c [scudo] Implement stricter separation of C vs C++
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.

Kostya Kortchinsky 9e917a13fb [scudo] Add a shared runtime
Summary:
Up to now, the Scudo cmake target only provided a static library that had to be
linked to an executable to benefit from the hardened allocator.
This introduces a shared library as well, that can be LD_PRELOAD'ed.
