[Ada] Remove excessive guards against inserting empty lists of actions

[Ada] Remove excessive guards against inserting empty lists of actions

[Marc Poulhiès]

[-- Attachment #1: Type: text/plain, Size: 320 bytes --]

Call to Insert_Actions with empty list does nothing, so there is no need to
guard against such calls. Code cleanup; behavior is unaffected.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* freeze.adb (Freeze_Itype): Remove excessive guard.
	* sem_ch5.adb (Analyze_Loop_Parameter_Specification): Likewise.
