[lworld] RFR: 8275331: [lworld] TestArrays.java fails IR verification on aarch64

[Tobias Hartmann]

IR verification fails after the recent merge with mainline because the fix for [JDK-8273825](https://bugs.openjdk.java.net/browse/JDK-8273825) needs to be applied to Valhalla specific matching rules.

I also problem listed `TestPostParseCallDevirtualization` until [JDK-8274973](https://bugs.openjdk.java.net/browse/JDK-8274973) is fixed.

Best regards,
Tobias
