7090654: nightly failures after 7086585
Reviewed-by:

I had made late changes to accessing of fields in InstanceKlass and
didn't rerun my tests so I create a mismatch between the indexing.
Some code was using i * 7 and others was using i.  I've corrected it
so it's using i consistently everything.  Tested with sajdi.

I screwed up the new of fields when we recreate a .class file from our
internal representation.  It should be unscaled.  Tested with
java/lang/instrument regression tests.  I had thought the tests I
originally ran exercised this path but I was wrong.
