Fix baseline computation for nested inline-blocks

This moves the check for overflow: <not visible> into
inlineBlockBaseline, so that the baseline gets correctly calculated for
an outer inline-block when an inner inline-block or block has
overflow: hidden.

We also do this if the inner block is not an inline-block -- this
matches Firefox behavior and is required for at least one website
(http://in.yahoo.com/).
