JDK-8341411 removed the slice parameter from GraphKit::make_load() and GraphKit::store_to_memory().

It might be possible to go even further and remove them from LoadNode::make and analogously in Store.

Then in the GC API it might not be necessary to pass adr_type anymore in:

C2AccessValuePtr addr(adr, adr_type);
 C2ParseAccess access(this, decorators | C2_READ_ACCESS, bt, obj, addr);
