This function doesn't do anything anymore (since rC288563) (in most cases, at least). We now have lvalue sub-objects adjustments that are outside of `MaterializeTemporaryExpr`, and i'm trying to see if there are any by comparing the variable type with the temporary type. If there are still any rvalue sub-object adjustments present in the AST, then i'd have to skip them, as an additional step.
