Hi,

   Please review the following patch:

      Bug: https://bugs.openjdk.java.net/browse/JDK-8233466

Webrev: http://cr.openjdk.java.net/~fyang/8233466/webrev.00/



When profiling return and parameters type from the interpreter on aarch64 platform, 'mdp' is loaded by test_method_data_pointer which is called by profile_return_type & profile_parameters_type.

It's not necessary to load mdo before calling __ profile_return_type or __ profile_parameters_type.



Passed tier1-3 testing.



Thanks,

Felix
