Milian Wolff 9a789a965a Optimize QObject::senderSignalIndex to only iterate the d->senders once. 
QObject::senderSignalIndex is, combined with ::sender(), the current
hotspot in the QWebChannel which makes heavy use of it in its 1-to-many
QSignalSpy implementation.

This patch optimizes the senderSignalIndex by only iterating over the
linked senders list once, instead of twice. I.e. it first iterated over
it to find the signal index, then again to find the sender to convert
to a method-offset.
