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`

Martin Povišer fa4a2b6b0d opt_expr: In clkinv loop ignore irrelevant cells early 
Each call to `handle_clkpol_celltype_swap` has a conversion of the
cell's type ID to an allocated string. This can sum up to a
non-negligible time being spent in the clkpol code even for a design
which doesn't have any flip-flop gates.

Martin Povišer 7a8a69b65c opt_expr: Revisit sorting in replace_const_cells 
Avoid building a cell-to-inbit map when sorting the cells, add a warning
if we are unable to sort, and move the code treating non-combinational
cells ahead of the rest (this means we don't need to pass
non-combinational cells to the TopoSort object at all).

Martin Povišer 030d639201 opt_mem, memory_*: Refuse to operate in presence of processes 
Processes can contain `MemWriteAction` entries which are invisible to
most passes operating on memories but which will be lowered to write
ports later on by `proc_memwr`. For that reason we can get corrupted
RTLIL if we sequence the memory passes before `proc`. Address that by
making the affected memory passes ignore modules with processes.
