gcc 5 and clang++-3.7 support sized deallocation from C++14. We are taking advantage of that by defining sized versions of operator delete. This is off by default so that if some existing programs that define own global operator delete without sized variant are not broken by tcmalloc's sized delete operator. There is also risk of breaking exiting code that deletes objects using wrong class (i.e. base class) without having virtual destructors.
