Previous logic relied on the fact that for most operations, for a given
lhs type, there was exactly one rhs type allowed, except for
multiplication. This is no longer true in the spec, so making this test
work is more complex now. Instead, we simplify the test by having it
take the cartesian product of all possible (type * type * op), and
skipping any triplet not found in the all_valid_cases table.
