c3b8de54da test: add tests for shiftadd and shiftmul 
This expands the part-select tests with one additional module.
It specifically tests the different variants of the `peepopt`
optimizations `shiftadd` and `shiftmul`.
Not all these cases are actually transformed using `shiftadd`,
including them also checks if the correct variants are rejected.

9ca57d9f13 peepopt: fix and refactor shiftadd 
- moved all selection and filtering logic to the match block
- applied less-verbose code suggestions
- removed constraint on number of bits in shift-amount
- added check for possible wrap-arround in the operation

aa9b86aeec peepopt: Add left-shift 'shiftmul' variant 
Add a separate shiftmul pattern to match on left shifts which implement
demuxing. This mirrors the right shift pattern matcher but is probably
best kept separate instead of merging the two into a single matcher.
In any case the diff of the two matchers should be easily readable.

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.

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).
