[lworld] RFR: 8294866: [lworld] Array classes access flags should include identiy bits [v2]

[Roger Riggs]

> Update java.lang.reflect.AccessFlag to return IDENTITY for array classes.
> The access flag bits for arrays come from the VM, hence the changes to HotSpot.

Roger Riggs has updated the pull request incrementally with one additional commit since the last revision:

  Tagged the new IDENTITY and STRICT_FIELD AccessFlags to be valid as of the `latest()` class file version number.
  They should float forward with releases until the first release in which Valhalla is integrated.
