// We must avoid ever having to call `force_from_dep_node()` for a
// `DepNode::codegen_unit`:
// Since we cannot reconstruct the query key of a `DepNode::codegen_unit`, we
// would always end up having to evaluate the first caller of the
// `codegen_unit` query that *is* reconstructible. This might very well be
// the `compile_codegen_unit` query, thus re-codegenning the whole CGU just
// to re-trigger calling the `codegen_unit` query with the right key. At
// that point we would already have re-done all the work we are trying to
// avoid doing in the first place.
// The solution is simple: Just explicitly call the `codegen_unit` query for
// each CGU, right after partitioning. This way `try_mark_green` will always
// hit the cache instead of having to go through `force_from_dep_node`.
// This assertion makes sure, we actually keep applying the solution above.
