r241432 - Teach mingw toolchain the msys2 mingw-w64 distribution C++ dirs.

[İsmail Dönmez]

This is without any patches (r241901-win64) and the original command
line is there:

clang -v -target x86_64-w64-mingw32 -isystem
 C:/mingw-w64-6.0.0/x86_64-w64-mingw32/include -isystem
 C:/mingw-w64-6.0.0/include/c++/6.0.0 -isystem
 C:/mingw-w64-6.0.0/include/c++/6.0.0/x86_64-w64-mingw32
 randomworks/windows/nic.c
