We need a way to walk chained method handles in the JVM to call the right methods and to generate required bytecode adapters for the compilers.

6906727: UseCompressedOops: some card-marking fixes related to object arrays
...
Introduced a new write_ref_array(HeapWords* start, size_t count) method that does the requisite MemRegion range calculation so (some of the) clients of the erstwhile write_ref_array(MemRegion mr) do not need to worry. This removed all external uses of array_size(), which was also simplified and made private. Asserts were added to catch other possible issues. Further, less essential, fixes stemming from this investigation are deferred to CR 6904516 (to follow shortly in hs17).
