The crate outlives map is computed during typeck and contains the
outlives of every item in the local crate. You should not use it
directly, because to do so will make your pass dependent on the
HIR of every item in the local crate. Instead, use
tcx.inferred_outlives_of()
to get the outlives for a particular
item.

For each struct with outlive bounds, maps to a vector of the predicate of its outlive bounds. If an item has no outlives bounds, it will have no entry.
