Gowin. Remove unnecessary modules
...
Primitives that are not planned for implementation for reasons of
belonging to old unsupported chips or representing composite complex IPs
rather than primitives are removed.
Also latches and large MUXes not planned for implementation.

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
$@))`.

Reduce comparisons of size_t and int

`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.
For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.

Drop timestamp in generate_bram_types_sim.py

I'm working on build reproducibility of Fedora packages, and this patch fixes
an issue observed in test rebuilds: the timestamp was set to the actual time
of the build, making builds nonreproducible.
Other "Generated by" strings do not include a timestamp, so drop it here too.
