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.

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).

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.

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.
