6bf9fc1817 Add -nocells flag to equiv_make and equiv_opt 
The -nocells flag skips cell equivalence checking and only checks wire
equivalence. This is useful when optimizations preserve functionality but
rename or restructure cells, avoiding false negatives in equivalence checking.

7ff5a9db2d equiv_opt: pass -D EQUIV when techmapping. 
This allows avoiding techmap crashes e.g. because of large memories
in white-box cell models.
