Thanks to Larry Doolittle <LRDoolittle@lbl.gov>. Add the LPM_MUX device, and integrate it with the ternary synthesis from Larry. Replace the lpm_mux generator in t-xnf.cc to use XNF EQU devices to put muxs into function units. Rewrite elaborate_net for the PETernary class to also use the LPM_MUX device.
and arrange in vvm for pin connections by name and instance number.
