I'm not overly fond of the conditionals (especially in error_operand_p) but I don't think it's reasonable to make IDENTIFIER_NODE bigger and penalize the other FEs just because the C++ FE is playing games with TREE_TYPE.
The C++ FE expects that we can check the TREE_TYPE of anything that appears as an expression, and uses IDENTIFIER_NODE to indicate a dependent name within templates. If you want to break TREE_TYPE on IDENTIFIER_NODE, you need to change the representation of dependent names so that we can continue to use TREE_TYPE on all expressions.
