Screenshot: Blur shows car without wheels

Recompiled Wine with the following CFLAGS: "-O2 -march=znver2", and noticed
that in Blur, the cars (shown in the menus and in the game) are rendered
without wheels. Before, I had compiled Wine compiled with "-O2
-march=ivybridge", and the wheels are rendered correctly.

It does not make a difference, if I use wined3d, d9vk or wine-nine-standalone.
But it makes a difference, if Wine's msvcr90, or Microsoft's MSVC runtime DLLs
are used - wheels are always shown correctly with MSVC runtime DLLs.
