Subject: Fix a warning

```
../gc.c:2342:45: warning: comparison of integers of different signs: 'short' and 'size_t' (aka 'unsigned long') [-Wsign-compare]
    GC_ASSERT(size_pools[pool_id].slot_size == slot_size);
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
```

Add cast to short, because `GC_ASSERT`s in `size_pool_for_size`
already use cast to short.
