Clang code-model shows errors when MSVC 2017 kit is selected

When using Qt Creator and a kit with MSVC 2017 as the compiler the Clang code model will show alot of errors. If the kit is switched to one with MingW 5.3 all errors disappears.

This is very annoying and disrupts the work when using Qt together with MSVC compiler, so much so that it is almost easier to code using MingW and just build with MSVC 2017.

Attached are two screenshots that shows the difference, the only change is changing the build kit.

An example project that shows this behaviour can be found here: https://gitlab.com/AndWass/qt-creator-clang-bug
