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.

quicklogic: Avoid carry chains in division mapping
...
The default mapping rules for division-like operations (div/divfloor/
mod/modfloor) invoke subtractions which can get mapped to carry chains
in FPGA flows. Optimizations across carry chains are weak, so in
practice this ends up too costly compared to implementing the division
purely in soft logic.
For this reason arrange for `techmap.v` ignoring division operations
under `-D NODIV`, and use this mode in `synth_quicklogic` to avoid carry
chains for divisions.

pmgen: Have a single make pattern
...
Remove duplicate %.pmg -> %_pm.h pattern. One of the duplicates overrode
the other, and in some conditions there were build races as to whether
the target directory for the generated header would exist. Instead have
a single rule which is properly generalized.
