There is no "bar checking algorithm for the lyrics": it is the normal
bar check.  Lyric ties are articulations: they are just attached to the
preceding notes.  They don't have a length of themselves.

Nothing is _dependent_ on the bar checks (I think there may be some
resynchronization option for when a warning is triggered, but it is off
by default).

At least with ties, they won't work.  It's conceivable that you can put
in \skip ... after a lyric tie in order to move forward to the time
where a bar check makes sense, but I haven't tried it, and it may well
throw off note/lyric synchronization altogether.
