element type until all sources of class exprs are tried. Use
class API rather than TREE_OPERAND. Look for class expressions
in ss->info by calling get_class_info_from_ss. After, obtain

element sizes are the same. Use earlier evaluation of

of the correct type. Obtain rhs vptr in all circumstances.

make maximum use of the vptr copy in place of assignment.
