        Description

        Fix memory ordering issues in C++ Interpreter as required for ppc.

        Issue StoreStore barriers after object initialization so that no partially initialized objects are visible.
        Also issue a StoreStore barrier after (constructor) calls so that final field initializations are visible.

        ---------------------------------

        This is preparation for PPC64 integration: http://openjdk.java.net/jeps/175
        This and following ppc64 changes will go into staging repository first and tested there: http://hg.openjdk.java.net/ppc-aix-port/stage/
