18ad56ef41 Add dffunmap pass. 
To be used with backends that cannot deal with fancy FF types (like blif
or smt).

6cd135a5eb opt_expr: Remove -clkinv option, make it the default. 
Adds -noclkinv option just in case the old behavior was actually useful
to someone.

cf60699884 synth_ice40: Use opt_dff. 
The main part is converting ice40_dsp to recognize the new FF types
created in opt_dff instead of trying to recognize the mux patterns on
its own.

The fsm call has been moved upwards because the passes cannot deal with
$dffe/$sdff*, and other optimizations don't help it much anyway.

a1a0abf52a equiv_induct: Fix up assumption for $equiv cells in -undef mode. 
Before this fix, equiv_induct only assumed that one of the following is
true:

- defined value of A is equal to defined value of B
- A is undefined

This lets through valuations where A is defined, B is undefined, and
the defined (meaningless) value of B happens to match the defined value
of A.  Instead, tighten this up to OR of the following:

- defined value of A is equal to defined value of B, and B is not
  undefined
- A is undefined
