Patch to synthesize unary ~ and the ternary operator.

Browse Source 
Thanks to Larry Doolittle <[email protected]>.

 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.
