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

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.
