2a3720921c Gowin. Fix GW5A ADCs. 
For these primitives, Gowin decided to use a different option for
describing ports—directly in the module header, i.e.

``` verilog
module ADC(input CLK);
```

instead of
``` verilog
module ADC(CLK);
input CLK;
```

Since this one-time parser becomes too confusing, it is easier to simply
add ADC descriptions as they are from a separate file, especially since
these primitives are only available in the GW5A series.

Test:
``` shell
yosys -p "read_verilog top.v; synth_gowin -json top-synth.json -family gw5a"
```

The old version of Yosys simply won't compile the design due to the lack
of port descriptions, while the new version will compile without errors.

64700dec65 Gowin. Disable unsupported BSRAM mode in GW5A 
All supported (and planned to be supported) GW5A series chips do not
support the 2: Read-before-Write write mode.

Here, we prohibit the generation of BSRAM with this mode.

3c2caffffe Make IdString refcounts a hashtable containing only the nonzero refcounts 
This saves space and doesn't cost very much since we hardly ever have nonzero refcounts any more.

It also allows for IdStrings with negative indexes, which we're going to add.
