__builtin_memmove (in non-type-punning cases). This is intended to permit libc++ to make std::copy etc constexpr without sacrificing the optimization that uses memcpy on trivially-copyable types. __builtin_strcpy and __builtin_wcscpy are not handled by this change. They'd be straightforward to add, but we haven't encountered a need for them just yet. llvm-svn: 338455
