Correct line width calculation with inline-block induced word spacing

Correct line width calculation with inline-block induced word spacing

A previous CL allowed word spacing to be added around inline-blocks.
However the line width calculation wasn't consistent with children placement,
and contents will overflow on the right side of the line if there was
inline-block induced word spacing.

This CL makes RenderBlockFlow::computeInlineDirectionPositionsForSegment to be
consistent with InlineFlowBox::placeBoxRangeInInlineDirection.
