// Test a case of a trait which extends the same supertrait twice, but
// with difference type parameters. Test then that when we don't give
// enough information to pick between these, no selection is made. In
// this particular case, the two choices are i64/u64 -- so when we use
// an integer literal, we wind up falling this literal back to i32.
