value-relation: Fix up relation_union [PR108447]
While looking at the PR, I've noticed one row in rr_union_table
is wrong. relation_union should be commutative, but due to that
bug is not. The following patch adds a self-test for that
property (fails without the first hunk) and fixes that line.
The actual floating point relation problem isn't fixed by this patch
though.
