LIRGenerator::generate_address contains code to simplify constant index/displacement. Code like the following line uses int which may overflow:
disp += index->as_constant_ptr()->as_jint() << shift;
We should use 64 bit integer variables on 64 bit platforms.
disp += index->as_constant_ptr()->as_jint() << shift;
