	* sem_ch6 (Analyze_Expression_Function): treat the function as
	Inline_Always, and introduce a subprogram declaration for it when it is
	not a completion.
	* inline.adb (Add_Inlined_Body): recognize bodies that come from
	expression functions, so that the back-end can determine whether they
	can in fact be inlined.
	* sem_util.adb (Is_Expression_Function): predicate to determine whether
	a function body comes from an expression function.
