[aarch64-port-dev ] RFC: 64 bit literal oops

[Stuart Monteith]

Thanks for taking a look. I've updated it here:

  http://cr.openjdk.java.net/~smonteith/oop64/webrev-20190214/

The stub code size needs to be increased to 14 instructions because of
the construction of 64-bit constants in the main code.

BR,
   Stuart
