Log:
	* exp_util.adb (Remove_Side_Effects): Also make a constant if we need
	to capture the value for a small not by-reference record type.
	* freeze.ads (Check_Compile_Time_Size): Adjust comment.
	* freeze.adb (Set_Small_Size): Likewise.  Accept a size in the range
	of 33 .. 64 bits.
	(Check_Compile_Time_Size): Merge scalar and access type cases. Change
	variable name in array type case.  For the computation of the packed
	size, deal with record components and remove redundant test.
	(Freeze_Array_Type): Also adjust packing status when the size of the
	component type is in the range 33 .. 64 bits.
	* doc/gnat_rm/representation_clauses_and_pragmas.rst: Turn primitive
	into elementary type throughout.  Minor tweaks.
	(Alignment Clauses): Document actual alignment of packed array types.
	(Pragma Pack for Arrays): List only the 3 main cases and adjust.  Add
	"simple" to the record case.  Document effect on non packable types.
	(Pragma Pack for Records): Likewise.  Add record case and adjust.
