Fix std detection for win32-clang-msvc

Browse Source 
clang-cl will never support C++ standards newer than
C++14 without these flags.
I didn't add them to msvc-based-version.conf because
on Windows, only clang-cl use the same flags with MSVC,
both ICC and MinGW have their own flags. So they are
clang-cl specific flags.
