Martin Povišer 038a5e1ed4 peepopt: Support shift amounts zero-padded from below 
The `opt_expr` pass running before `peepopt` can interfere with the
detection of a shiftmul pattern due to some of the bottom bits of the
shift amount being replaced with constant zero. Extend the detection to
cover those situations as well.

Martin Povišer a0c3be3aae peepopt: Drop unused 'initbits' code 
Drop code that was once used by the 'dffmux' pattern but now is unused
after that pattern has been obsoleted by the 'opt_dff' pass.

Wanda c36cf9c5ac write_verilog: avoid emitting empty cases. 
The Verilog grammar does not allow an empty case.  Most synthesis tools
are quite permissive about this, but Quartus is not.  This causes
problems for amaranth with Quartus (see amaranth-lang/amaranth#931).

Martin Povišer 0434f9d3d1 booth: Fix vacancy check when summing down result 
In commit fedd12261 ("booth: Move away from explicit `Wire` pointers")
a bug was introduced when checking for vacant slots in arrays holding
some intermediate results. Non-wire SigBit values were taken to imply
a vacant slot, but actually a constant one can make its way into those
results, if the multiplier cell configuration is just right. Fix the
vacancy check to address the bug.
