Martin Povišer fed2720999 synth_lattice: Optimize flip-flop memories better 
After `memory_map` maps memories to flip-flops we need to let `opt`
remove undef muxes, otherwise we block enable/reset signal inference by
`opt_dff` which is in detriment to QoR.

Martin Povišer ee3a4ce14d synth_lattice: Merge NOT gates on DFF control signals 
`dfflegalize` will emit NOT gates to drive control signals on flip-flops
when mapping to supported flip-flop polarities. Typically in a design
this will produce a number of NOT gates driven by the same signal. For
one reason or another ABC doesn't fully cancel this redundancy during
LUT mapping. Insert an explicit `opt_merge` pass to improve synthesis
QoR.

Jannis Harder d415b4d98a cli: Cleanups for tcl argument handling 
* Keep the previous behavior when no tcl script is used
* Do not treat "-" as a flag but as a positional argument
* Keep including <unistd.h> as it's also used for other functions (at
  least for the emscripten build)
* Move the custom getopt implementation into the Yosys namespace to
  avoid potential collisions

phsauter 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.

phsauter 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

Martin Povišer 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.

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.
