RFR: 8339542: compiler/codecache/CheckSegmentedCodeCache.java fails

[Lutz Schmidt]

On systems with large page sizes, the minimum size required for non-method code heap may be larger than the value preset in the test. This effect is triggered by JDK-8334564, which increases the required minimum size such that it will not be rounded down to zero.

SAP-internal testsuite completed with no related errors. In particular, CheckSegmentedCodeCache.jave succeeds.
