ART: Change RETURN_OBJECT verification for arrays
Arrays appear to be valid (as according to spec), even if their
components are erroneous. If a component is erroneous, it may not
have loaded superclass or interface information, and so fail a
direct check for assignability.
Add a cutout that checks whether the declared return-type or the
actual return-type are arrays with erroneous components (and if so,
have the same 'depth'). In that case, generate a soft instead of a
hard error.
Also includes a fix to DumpClass.
