The MH+VH form should be much more lightweight: MH and VH are just MemberName 
references.

I wonder if we can advertise the MH+VH version as an indy BSM:

public static CallSite lazyAccessor(Lookup lookup, String unused, MethodType 
callType, VarHandle field, MethodHandle computer)


The CallSite would be constant, with 
`StableIntFieldUpdaterVarHandle.applyAsInt` bound to the specific updater. This 
way, we can even defer the creation of the updater.
