[Ada] Fix type mismatch warnings during LTO bootstrap #5

gcc/ada/

	* raise-gcc.c (__gnat_others_value): Remove const qualifier.
	(__gnat_all_others_value): Likewise.
	(__gnat_unhandled_others_value): Likewise.
	(GNAT_OTHERS): Cast to Exception_Id instead of _Unwind_Ptr.
	(GNAT_ALL_OTHERS): Likewise.
	(GNAT_UNHANDLED_OTHERS): Likewise.
	(Is_Handled_By_Others): Change parameter type to Exception_Id.
	(Language_For): Likewise.
	(Foreign_Data_For): Likewise.
	(is_handled_by): Likewise.  Adjust throughout, remove redundant
	line and fix indentation.
	* libgnat/a-exexpr.adb (Is_Handled_By_Others): Remove pragma and
	useless qualification from parameter type.
	(Foreign_Data_For): Likewise.
	(Language_For): Likewise.
