RFR(XS) 8173673: Fix comparison input types in GraalHotSpotVMConfigNode.inlineContiguousAllocationSupported()

[Igor Veresov]

The change got a bit bigger after the reviews on GitHub.
So, I’m revising the webrev: http://cr.openjdk.java.net/~iveresov/8173673/webrev.01/
Relevant discussion here: https://github.com/graalvm/graal-core/pull/249

Thanks,
igor
