Implements PR40180. clang-cl has one minor behavior difference with cl with this change. Clang allows the user to enable the C++17 feature of aligned allocation without enabling all of C++17, but MSVC will not call the aligned allocation overloads unless -std:c++17 is passed. While our behavior is technically incompatible, it would require making driver mode specific changes to match MSVC precisely, and clang's behavior is useful because it allows people to experiment with new C++17 features individually. Therefore, I plan to leave it as is. llvm-svn: 351249
