[COMMITTED] ada: Minor tweaks for comparison operators

[COMMITTED] ada: Minor tweaks for comparison operators

[Marc Poulhiès]

From: Eric Botcazou <ebotcazou@adacore.com>

No functional changes.

gcc/ada/

	* gen_il-gen-gen_nodes.adb (N_Op_Boolean): Fix description.
	* sem_ch4.adb (Analyze_Comparison_Equality_Op): Tidy up.
	* sem_ch12.adb (Copy_Generic_Node): Use N_Op_Compare subtype.

Tested on x86_64-pc-linux-gnu, committed on master.
