Deduplicate code for break-after and break-before propagation.

Move it into MovePastBreakpoint(), so that all algorithms get this for
free. I realized that this actually fixes a bug with break-before on
first-child spanners in nested multicol, so wrote a few tests. Decided
to add similar break-after tests as well, and discovered that this still
fails, and it's not a new bug. Filed bug 1191124 for this.
