The code removed by this patch was a leftover from the time when we tried to
emulate MOVA with a plain ARL, which only supports one source in plain ARB.
This breaks the more sophisticated MOVA and 4 component ADDR register we have
now however.

comctl32: Explicitly initialize visible order of a newly added item, force visible order recalculation on redraw.

comctl32: Do not redraw treeview in TVM_INSERTITEM handler if bRedraw is not set, trigger the redraw on WM_SETREDRAW/TRUE.

Simply changing Z-order as we encounter windows is not sufficient to
ensure correct ordering, we have to rebuild the list from scratch.
