Philippe Sauter 68a9aa7c29 peepopt: handle offset too large in `shiftadd` 
If the offset is larger than the signal itself,
meaning the signal is completely shifted out,
it tried to extract a negative amount of bits from the old signal.

This RTL pattern is suspicious since it is a complicated way of
arriving at a constant value, so we warn the user.

Docs: work on selections.rst 
Highlighting the difference between `select prod %ci` and `select prod %ci2` by

Docs: some restructure of advanced section 
- Filling out index descriptions for `using_yosys` and `using_yosys/synthesis`.
- To discourage skipping over these index pages, the toctree in
  `using_yosys/index` is hidden and instead has inline links to the two
  subsections.
- Tidying todos.
- Moves technology mapping to `techmap_synth`, leaving the techmap by example in
  the internals section. `yosys_flows` gets split up, with the coarse-grain
  intro replaced by `synthesis/index`, the extract pass moving to
  `synthesis/extract` and model checking to `more_scripting/model_checking`.

`code_examples/macro_commands` against the current yosys build. Format similar
