Add PRIVATE keyword in target_link_libraries to prevent CMake Error on Windows.
While trying to compile llvm/clang on Windows, the following CMake error occurred. The reason is a missing PUBLIC/PRIVATE/INTERFACE keyword in target_link_libraries.
`
CMake Error at utils/KillTheDoctor/CMakeLists.txt:5 (target_link_libraries):
The keyword signature for target_link_libraries has already been used with
the target "KillTheDoctor". All uses of target_link_libraries with a
target must be either all-keyword or all-plain.
The uses of the keyword signature are here:
* cmake/modules/AddLLVM.cmake:771 (target_link_libraries)

The system API's will be shifted over to returning an error_code, and returning
other return values as out parameters to the function.
Code that needs to check error conditions will use the errc enum values which
are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are
compatable with the error codes in WinError.h due to some magic in system_error.
An example would be:
if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool.
handle_error(ec);
}
