QtWidgets: replace some index-based for loops with C++11 range-for
This needs to be handled a bit carefully, because Qt containers
will detach upon being iteratoed over using range-for.
In the cases of this patch, that cannot happen, because all
containers are marked as const (either by this patch or before).
Separate patches will deal with other situations.
Apart from being more readable, range-for loops are also the
most efficient for loop.
This patch shaves almost 2K of text size off an optimized Linux
AMD64 GCC 4.9 build.
