* Fix truncation of output seed value from 64 bits to 32 bits (int
instead of uint64) when written to json file.
* Fix input seed value conversion when --seed option is used.
* Remove input seed value scrambling (use of rngseed()) when --seed
or --randomize-seed option is used since the output seed value will
be the scrambled value and not the seed that was actually supplied
or generated.
* Gowin. Implement the EMCU primitive.
Add support for the GW1NSR-4C's embedded Cortex-M3 processor. Since it
uses flash in its own way, we disable additional flash processing for
this case.

* Gowin. Add DHCEN primitive.
This primitive allows you to dynamically turn off and turn on the
networks of high-speed clocks.
This is done tracking the routes to the sinks and if the route passes
through a special HCLK MUX (this may be the input MUX or the output MUX,
as well as the interbank MUX), then the control signal of this MUX is
used.

* Gowin. Change the DHCEN binding
Use the entire PIP instead of a wire - avoids normalisation and may also
be useful in the future when calculating clock stuff.

Some Clocks PIPS were not created due to a check for the presence of a
delay class, now all wires are attributed to the class so that there is
no longer any need for this check.

* Gowin. Implement the UserFlash primitive
Some Gowin chips have embedded flash memory accessible from the fabric.
Here we add primitives that allow access to this memory.
