Consistent resolution of cyclic percentages in min sizing properties
The spec says that cyclic percentages in min sizing properties should
be resolved against zero when computing intrinsic contributions.
We were already doing that in the inline axis, but we were treating
the entire expression as auto in the block axis.
With this patch we will follow the spec in both axes. But note that
browsers don't follo the spec in either axis, so we may have to revisit
(see w3c/csswg-drafts#10969).
calc-min-height-block-1.html now fails because it tests what browsers
do instead of what the spec says.
