RFR(S): 8213527: [testbug] Fix tests using UseCompressedOops for 32-bit.

[Lindenmaier, Goetz]

Hi,

A few tests that use the UseCompressedOops flag are failing on 32-bit platforms.

Adapt the test script of PrintMetaspaceDcmd to only test the relevant case on 32-bit and to omit the unsupported flags.

Adapt VMProps.vmOptFinalFlag to return 'false' on 32-bit for UseCompressedOops. The flag is not defined at all in 32-bit builds, thus currently 'null' is returned by vmOptFinalFlag.

Best regards,
