RFR(xxs) 8074543 Missing symbol "objArrayOopDesc::obj_at" when buiding with CPP Interpreter

[Thomas Stüfe]

Hi all,

please review this tiny change to fix a build error when building with the
CPP interpreter.

webrev:
http://cr.openjdk.java.net/~stuefe/webrevs/8074543/webrev.01/

bug:
https://bugs.openjdk.java.net/browse/JDK-8074543

bytecodeInterpreter.cpp misses include "objArrayOop.inline.hpp", so the
inline definition of this function is missing.

Kind Regards, Thomas
