build crash after extending oopDesc

[Krystal Mok]

David,

If this patch [1] resembles your change, then what I saw was that the VM
would build all right, but would fail running test_gamma right at the end
of the build process.

The problem was caused by arrayOopDesc::length_offset_in_bytes(), as noted
[2]. test_gamma runs fine if I drop a .hotspotrc file specifying
-UseCompressedOops in it, which confirms the problem.
