	* layout.ads (Set_Elem_Alignment): Add Align parameter defaulted to 0.
	* layout.adb (Set_Elem_Alignment): Likewise.  Use M name as maximum
	alignment for consistency.  If Align is non-zero, use the minimum of
	Align and M for the alignment.
	* cstand.adb (Build_Float_Type): Use Set_Elem_Alignment instead of
	setting the alignment directly.

	* sem_prag.adb (Analyze_Pragma, case Check): Defer evaluation of the
	optional string in an Assert pragma until the expansion of the pragma
	has rewritten it as a conditional statement, so that the string
	argument is only evaluaed if the assertion fails. This is mandated by
	RM 11.4.2.
