tree-if-conv.c:tree_if_convert_stmt uses TREE_OPERAND (t, 1)
for t being GOTO_EXPR like so:

    case GOTO_EXPR:
      /* Unconditional goto */
      add_to_predicate_list (bb_for_stmt (TREE_OPERAND (t, 1)), cond);
      bsi_remove (bsi);
      cond = NULL_TREE;
      break;

GOTO_EXPR has only one operand, so TREE_OPERAND (t, 1) is wrong.

Also, nonlocal gotos are represented using __builtin_nonlocal_goto,
computed gotos are represented using GOTO_EXPR, and
all other gotos are represented implicitly.

I don't think the code there is designed to handle computed gotos,
but I could be wrong.
