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

[David Holmes]

Hi Goetz,

Boris already has this issue out for review under:

8213410: UseCompressedOops @requirement check fails fails on 32-bit system

We're currently waiting on feedback from jtreg folk on exactly how 
@requires is expected to work to see which way to fix it cleanly.

I would not want to special case UseCompressedOops in VMProps.java

Thanks,
David
