[11u] RFR: 8246153: TestEliminateArrayCopy fails with -XX:+StressReflectiveCode

[Lindenmaier, Goetz]

Hi,

I would like to downport this for parity with 11.0.9-oracle.

The change to opto does not apply at all, but I think I found the
Correct code to fix:

http://cr.openjdk.java.net/~goetz/wr20/8246153-TestEliminateArrayCopy-jdk11/01/

I can reproduce the error with the modified test without the fix, and
adding the fix the test passes.

Please review.

Best regards,
