Subject: [PATCH] Handle signedness of struct members

struct members are currently always treated as unsigned. This leads to
incorrect behavior in contexts where the sign makes a difference. E.g.

```
struct packed {
  int x;
} s;

s.x = -1;
if (s.x > 0) $display("FAILED");
```

Query the signedness of the struct member form the type of the member.
