Marcelina Kościelnicka 38a0c30d65 Get rid of dffsr2dff. 
This pass is a proper subset of opt_rmdff, which is called by opt, which
is called by every synth flow in the coarse part.  Thus, it never
actually does anything and can be safely removed.

Eddie Hung a8ab74285b zinit: handle $__DFFS?E?_[NP][NP][01] too 2020-04-14 13:08:23 -07:00
Marcelina Kościelnicka 6c16fd760b opt_expr: Add more $alu optimizations. 
Detect the places in the $alu where the carry bit is constant (due to
const A[i] == B[i] ^ BI) and split it into smaller $alu at these points.

Also, make the existing const-carry detection for low bits more generic
(now handles cases where both BI and CI are constant, but not equal to
one another).

Fixes #1912.

Marcelina Kościelnicka 516857f3ba [NFCI] Deduplicate builtin FF cell types list 
A few passes included the same list of FF cell types.  Make it a global
const instead.

The zinit pass also seems to include a list like that, but given that
it seems to be completely broken at the time (see #1568 discussion),
I'm going to pretend I didn't see that.
