qv4: assign split of edges to loop header to the correct group

(i.e assign split edges to the correct loop group, now for real)
The fix of 25b6fae1eb26645a30b3e7e254ce0b585757351c did try fix QTBUG-41766
and simplify the logic to assign the inserted statement to a loop group.
Unfortunately that was incorrect if the target basic block starts a group.
In that case if the source was already inside the group we should add it
to the target basic block, otherwise to the one containing the target
block (as before).
There was no visible regression caused by this.
