You're making this too easy for us.  I'll hardly have to make any 
changes to the FNF generator.  :-)

So bit selection is performed by IVL_LPM_PART.  Does ivl_lpm_base point 
to the MSB or the LSB of the new vector?

Also, is concatenation in the mix yet?  I didn't see it listed as a new 
LPM.  Or is it handled elsewhere?
