No, if you want the Itanium C++ ABI, use *-*-mingw32 in the triple.
This change effectively eliminates two possible invalid option combinations:
mingw + -cxx-abi microsoft (silly)
win32 + -cxx-abi itanium (clang's old default)
Both of these ABIs were invalid and subtly broken, as they were a
combination of some C ABI rules covered by the triple and some C++ ABI
rules covered by the other flag.
