Save memory by re-using empty TagInfo (and subclasses) arrays.
Arrays of TagInfo (and subclasses) often tend to be empty, as many
members simply won't have any of the relevant tags.
Re-using empty arrays saves potentially a dozen or more megabytes
for large projects.
Also some minor performance tweaks the Javadoc comment parsing.
