Hmmm...

  int main (void)
  {
      int a = 0;
      unsigned b = (a * 64 & 192) | 63;
      return 0;
  }
works (i.e. 63 without the U).
I suspect there's something dodgy with the implementation of
mask_with_tz (tree type, double_int x, double_int y) in fold-const.c that I
added with r202652.

Interestingly, the wide-int branch that rewrites that function to use the new
wide-int interface makes this ICE go away.
