Use RGB64 qdrawhelper routines for unpremultiplied formats
The ARGB32PM code-path doesn't have enough precision to accurately
render ARGB32 images, but the RGB64 code-path does. Since this is
already a slow configuration and the most costly part is the conversion
we can switch to the more accurate code-path for little cost.
