[11u] RFR: 8214512: ARM32: Jtreg test compiler/c2/Test8062950.java fails on ARM

[Christoph Göttschkes]

Hi,

please review this backport of JDK-8214512 to 11u:

Bug: https://bugs.openjdk.java.net/browse/JDK-8214512
Original commit: https://hg.openjdk.java.net/jdk/jdk12/rev/5da72d7e0e80

Webrev: https://cr.openjdk.java.net/~cgo/8214512/webrev.11u.00/

As already mentioned by Aleksey in the bug report, this test case also fails on 11u,
which is fixed by this backport.

The backport is not clean, because in 11u, the arm64 CPU type is still present.
Adjusting the backport was fairly straight forward.

Tested tier1 on Linux/ARMv7-A

Thanks,
Christoph
