Hoa Nguyen c1205ebc42 Initialize area stats in stat pass 
Currently, the area variables in the stat struct are not initialized.
This caused the area stats occasionally being an erroneous value.

George Rennie bdb5d45591 proc_dff: respect sync rule priorities when generating complex dffsrs 
* This fixes #4560, where previously the order that sync rules were
  processed in depended on the order they were pulled out of a std::map.
  This PR changes this to process them in the order they are found in,
  respecting the priorities among the async signals

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).

Philippe Sauter 2f0f10cb87 peepopt: limit padding from shiftadd 
The input to a shift operation is padded.
This reduced the final number of MUX cells
but during techmap it can create huge
temporary multiplexers in the log shifter.
This significantly increases runtime and resources.

A limit is added with a warning when it is used.

Jannis Harder 2bd889a59a formalff -setundef: Fix handling for has_srst FFs 
The `has_srst`` case was checking `sig_ce` instead of `sig_srst` due to
a copy and paste error.

This would crash when `has_ce` was false and could incorrectly determine
that an initial value is unused when `has_ce` and `has_srst` are both
set.
