           Summary: importC: .di generation does not place parentheses

I was able to add 4 lines to compiler/src/dmd/hdrgen.d to fix the problem. But
I don't know if that fix is complete or has bad side-effects. (never worked
with dmd code base before)

C-code:

struct S
{
  int x;
};
const struct S fun(int y);


.di file:
//...
const S fun(int y);
//...

The above code doesn't compile. It should be instead:
//...
const (S) fun(int y);
//...
