[Ada] Remove unnecessary special-casing of GNATprove expansion

2020-06-17  Piotr Trojanek  <trojanek@adacore.com>

gcc/ada/

	* checks.adb (Generate_Range_Check): Simplify redundant
	condition.
	* sem_ch3.adb (Check_Initialization, Process_Discriminants):
	Likewise.
	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): Likewise.
