56efdb4596 compiler: identify array index expressions in lvalue context 
Update the Mark_lvalue_varexprs visitor class (used in
    Assignment_statement::do_get_backend) to identify
    Array_index_expression's that appear on the left hand side of
    assignments, then pass this context info on when invoking
    Array_type::get_value_pointer.
