This fixes a compiler crash
IllegalStateException: Captured type for incorporation shouldn't escape
from incorporation
The crash occurs when a captured type with status FOR_INCORPORATION
is two layers deep inside a captured type with status FROM_EXPRESSION.
We first check if approximation is required for the most outer captured
type in AbstractTypeApproximator.approximateCapturedType.
Then we encounter the second captured type with status FROM_EXPRESSION
in AbstractTypeApproximator.approximateParametrizedType.
At this point, we stop checking and miss the third captured type with
status FOR_INCORPORATION.
Unfortunately, we can't check recursively if nested captured types
need to be approximated because of types with recursive super types
(the original reason why the extra check was introduced).
That's why we restrict the second check to types with recursive
super types, effectively restoring the previous behavior for all other
types.
