RFR(S) [downport 11]: 8213410: UseCompressedOops requirement check fails fails on 32-bit system

[Lindenmaier, Goetz]

Hi,

I need a review to downport 8213410.
8213410 fixes disabling tests for UseCompressedOops on 32-bit platforms.

In jdk12, "@requires vm.bits == 64" was introduced to CompressedClassPointers.java
by "8208655: use JTreg skipped status in hotspot tests". Because of this change,
8213410 does not apply properly.
To fix this, I introduce "@requires vm.bits == 64" to this test in jdk11, too.

Best regards,
