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.

Merge pull request #1845 from YosysHQ/eddie/kernel_speedup

f68985f997 deminout: prevent any constant assignment from demoting to input 
Before this patch,

```
module top(inout io);
assign io = 1'bx;
endmodule
```

would have the `io` pin demoted to input (same happens for `1'bz`,
but not for `1'b0` or `1'b1`), resulting in check failures later on.

Part of fix for #1841.
