[Ada] Minor cleanup in repinfo unit

This removes the Truth_Andif_Expr and Truth_Orif_Expr codes for expressions
handled by the repinfo unit, since they are redundant with Truth_And_Expr
and Truth_Or_Expr respectively in this context.  No functional changes.

gcc/ada/

	* repinfo.ads (TCode): Adjust range.
	(Truth_Andif_Expr): Remove.
	(Truth_Orif_Expr): Likewise.
	(Truth_And_Expr .. Dynamic_Val): Adjust value.
	* repinfo.adb (Print_Expr): Remove handling of Truth_{And,Or}if_Expr.
	(Rep_Value): Likewise.
	* repinfo.h (Truth_Andif_Expr): Remove.
	(Truth_Orif_Expr): Likewise.
	(Truth_And_Expr .. Dynamic_Val): Adjust value.
	* gcc-interface/decl.c (annotate_value) <TRUTH_ANDIF_EXPR>: Fall
	through to TRUTH_AND_EXPR case.
	<TRUTH_ORIF_EXPR>: Fall through to TRUTH_OR_EXPR case.
