opt_expr: Fix #4590 
If all the (non-select) inputs of a `$_MUX{4,8,16}_` are undefined, replace it, just like we do for `$mux` and `$_MUX_`.
Add `tests/opt/opt_expr_mux_undef.ys` to verify this.

This doesn't do any const folding on the wide muxes, or shrinking to less wide muxes.  It only handles the case where all inputs are 'x and the mux can be completely removed.

Martin Povišer fa4a2b6b0d opt_expr: In clkinv loop ignore irrelevant cells early 
Each call to `handle_clkpol_celltype_swap` has a conversion of the
cell's type ID to an allocated string. This can sum up to a
non-negligible time being spent in the clkpol code even for a design
which doesn't have any flip-flop gates.

Martin Povišer 7a8a69b65c opt_expr: Revisit sorting in `replace_const_cells` 
Avoid building a cell-to-inbit map when sorting the cells, add a warning
if we are unable to sort, and move the code treating non-combinational
cells ahead of the rest (this means we don't need to pass
non-combinational cells to the TopoSort object at all).

Rasmus Munk Larsen 0a37c2a301 Fix translation bug: The old code really checks for the presense of a node, not an edge in glift and flatten. 
Add back statement that inserts nodes in order in opt_expr.cc.

Rasmus Munk Larsen e0042bdff7 Speed up TopoSort. The main sorting algorithm implementation in TopoSort::sort_worker is 11-12x faster. Overall, the complete sequence of building the graph and sorting is about 2.5-3x faster. The overall impact in e.g. the replace_const_cells optimization pass is a ~25% speedup. End-to-end impact on our synthesis flow is about 3%. 2023-09-20 15:49:05 -07:00
