Avoid Cache*LoweringInfo pass when there's no GET/PUT/INVOKE.
Add new data flow flags indicating instance/static field
access. Record merged flags of all insns and use them to skip
the CacheFieldLoweringInfo pass if the method uses no fields
and the CacheMethodLoweringInfo pass if it has no invokes.
