John Lindgren 36aaf851ff Optimize QIconLoader::findIconHelper() 
Profiling QIconLoader::findIconHelper() shows that a significant portion of CPU time is being spent in
QDir::exists(), which creates a new QFileInfo object for the sole purpose of determining whether the passed-in
file path is relative or absolute, and then calls QFile::exists(). In this context, we can just as easily
generate the absolute path and call QFile::exists() directly, avoiding the creation of extra QDir and QFileInfo
objects.
