[9] RFR(S): 8060479: [TESTBUG] compiler/codecache/CheckSegmentedCodeCache.java test fails with product build

[Vladimir Kozlov]

CodeCacheMinimumUseSpace is different for Zero. There is WB API which returns options value getUintxVMFlag() you can use 
to calculate value minSize.

8046809 changes will change min_code_cache_size value again (removes CodeCacheMinimumFreeSpace). Let Albert know to 
modify this test again.

Thanks,
Vladimir
