Patch to synthesize LPM_ADD_SUB from expressions,
...
Thanks to Larry Doolittle. Also handle constants
in expressions.
Synthesize adders in XNF, based on a patch from
Larry. Accept synthesis of constants from Larry
as is.

Patch to synthesize unary ~ and the ternary operator.
...
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.

Generate OBUF or IBUF attributes (and the gates
...
to garry them) where a wire is a pad. This involved
figuring out enough of the netlist to know when such
was needed, and to generate new gates and signales
to handle what's missing.

Add the nobufz function to eliminate bufz objects,
...
Object links are marked with direction,
constant propagation is more careful will wide links,
Signal folding is aware of attributes, and
the XNF target can dump UDP objects based on LCA
attributes.
