b022fe61a7 opt_dff: fix sequence point copy paste bug 
Newer GCCs emit the following warning for opt_dff:

    passes/opt/opt_dff.cc:560:17: warning: operation on ‘ff.Yosys::FfData::has_clk’ may be undefined [-Wsequence-point]
      560 |      ff.has_clk = ff.has_ce = ff.has_clk = false;
          |      ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Which is correct: the order of whether the read or write of has_clk
occurs first is undefined since there is no sequence point between them.

This is almost certainly just a typo/copy paste error and objectively
wrong, so just fix it.

0aad88a2fb Add clean_zerowidth pass, use it for Verilog output. 
This should remove instances of zero-width sigspecs in the netlist,
avoiding problems in the Verilog backend with emitting them.

See #3103.

e833c6a418 verilog: use derived module info to elaborate cell connections 
- Attempt to lookup a derived module if it potentially contains a port
  connection with elaboration ambiguities
- Mark the cell if module has not yet been derived
- This can be extended to implement automatic hierarchical port
  connections in a future change

3efc14f5ad dfflegalize: remove redundant check for initialized dlatch 
This if condition is repeated verbatim, and I can't imagine a legitimate

4e70c30775 FfData: some refactoring. 
- FfData now keeps track of the module and underlying cell, if any (so
  calling emit on FfData created from a cell will replace the existing cell)
- FfData implementation is split off to its own .cc file for faster
  compilation
- the "flip FF data sense by inserting inverters in front and after"
  functionality that zinit uses is moved onto FfData class and beefed up
  to have dffsr support, to support more use cases

63b9df8693 kernel/ff: Refactor FfData to enable FFs with async load. 
- *_en is split into *_ce (clock enable) and *_aload (async load aka
  latch gate enable), so both can be present at once
- has_d is removed
- has_gclk is added (to have a clear marker for $ff)
- d_is_const and val_d leftovers are removed
- async2sync, clk2fflogic, opt_dff are updated to operate correctly on
  FFs with async load

9cbff3a4a9 opt_merge: Remove and reinsert init when connecting nets. 
Mutating the SigMap by adding a new connection will throw off FfInitVals
index.  Work around this by removing the relevant init values from index
whenever we connect nets, then re-add the new init value.

Should fix #2920.
