Description
Once JDK-8315003 is we, we should think about adding value type tests for the cases in compiler/c2/irTests/scalarReplacement/AllocationMergesTests.java.

There is currently a blocking bug (JDK-8335977) which first should be fixed in mainline. This bug fix should probably extend compiler/c2/irTests/scalarReplacement/AllocationMergesTests.java anyway and add deoptimization points together with verification code to ensure that the debug info is correct. Once this is done, we can extend this test with value types.
