hierarchy: Derive abstract cells in top mod
Previously abstract cells would only be derived if there was no top module declared, this means that `-check` would miss certain kinds of errors that it would normally detect.  This fixes #4927.

Jannis Harder 37aa2e6cd8 abstract: Wire vs port offset confusion bugfix
This fixes the offsets_to_abstract collection in abstract_state so that
it now works the same way as in abstract_value which was already
correct.

pmgen: Move passes out of pmgen folder
- Techlib pmgens are now in relevant techlibs/*.
- `peepopt` pmgens are now in passes/opt.
- `test_pmgen` is still in passes/pmgen.
- Update `Makefile.inc` and `.gitignore` file(s) to match new `*_pm.h` location,
  as well as the `#include`s.
- Change default `%_pm.h` make target to `techlibs/%_pm.h` and move it to the
  top level Makefile.
- Update pmgen target to use `$(notdir $*)` (where `$*` is the part of the file
  name that matched the '%' in the target) instead of `$(subst _pm.h,,$(notdir
  $@))`.

Martin Povišer 652a1b9806 macc: Stop using the B port
The B port is for single-bit summands. These can just as well be
represented as an additional summand on the A port (which supports
summands of arbitrary width). An upcoming `$macc_v2` cell won't be
special-casing single-bit summands in any way.

In preparation, make the following changes:

 * remove the `bit_ports` field from the `Macc` helper (instead add any
   single-bit summands to `ports` next to other summands)

 * leave `B` empty on cells emitted from `Macc::to_cell`
