w32_createwindow originally used f->top_pos and f->left_pos for the
top and left positions of the frame.  It now uses advises Windows'
window manager to position the frame itself unless there are values
for top or left positions set in initial-frame-alist or
default-frame-alist.  Because top and left positions passed to
make-frame are not added to these variables they are currently not
used.  Unfortunately I forgot this case when implementing the changes
in w32_createwindow.  Mitsuharu's suggestion could be a way to remedy
the problem IIUC.
