c++: Some cp-tree.def comment fixes

While reading the fold expression and concept tree comments, I found
various spots referring to non-existent macros etc.

The following patch attempts to sync that with what is actually implemented.

2024-07-22  Jakub Jelinek  <jakub@redhat.com>

	* cp-tree.def (UNARY_LEFT_FOLD_EXPR): Use FOLD_EXPR_MODIFY_P instead
	of FOLD_EXPR_MOD_P or FOLDEXPR_MOD_P in the comment.  Comment
	formatting fixes.
	(ATOMIC_CONSTEXPR): Use CONSTR_INFO instead of ATOMIC_CONSTR_INFO
	and ATOMIC_CONSTR_MAP instead of ATOMIC_CONSTR_PARMS in the comment.
	Comment formatting fixes.
	(CONJ_CONSTR): Remove comment about third operand.  Use CONSTR_INFO
	instead of CONJ_CONSTR_INFO and DISJ_CONSTR_INFO.
	(CHECK_CONSTR): Use CHECK_CONSTR_ARGS instead of
	CHECK_CONSTR_ARGUMENTS.
