If libc++ is built as a DLL, calls to operator new within the DLL aren't overridden if a user provides their own operator in calling code. Therefore, the alloc counter doesn't pick up on allocations done within std::string, so skip that check if running on windows. (Technically, we could keep the checks if running on windows when not built as a DLL, but trying to keep the conditionals simple.) Differential Revision: https://reviews.llvm.org/D100219
