dtrace support will not work after sharing is putback,
so there will be a need to make it working again.

For details, please, see Ken's email bellow:

Fred's made the needed changes so the files compile but they won't work yet.
The bug ID under which we will be checking in the class data sharing code is

4416624: multiple JVM runtimes do not share memory between themselves

The sharing putback makes changes to several data structures but I think the
only relevant change for the dtrace code is that methodOops have been split
into two pieces, the read-write portion (still called methodOop) and the
read-only portion (called constMethodOop). The constMethodOop contains the
unchanging data including the bytecodes. The read-write methodOop points to
the constMethodOop and the frame points to the read-write methodOop. There is
a webrev of the current code at
http://analemma.sfbay/net/animorphic/export/kbr/webrevs/class_data_sharing/2/
though we're going to do some cleanup of the SCCS deltas before sending it
out for broader review in a day or so.
