Fix some synth_* help messages
...
Mostly memory_libmap arg checks; puts the checks into an else block on the `if (help_mode)` check to avoid cases like `synth_ice40` listing `-no-auto-huge [-no-auto-huge]`.
Also fix `map_iopad` section being empty in `synth_fabulous`.

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.

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.
