RFR(S): 8222128: [lworld] Assertion failure in ci with flattenable non-flattened field inside a flattened field

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8222128
http://cr.openjdk.java.net/~thartmann/8222128/webrev.00/

The assert is too strong. Fields inside a flattened field can be non-flattened but flattenable.

Thanks to Fred for reporting.

Thanks,
Tobias
