	* sem_ch3.adb (Analyze_Number_Declaration): Call Analyze_Dimension,
	to propagate dimension information from expression to named
	number.
	* sem_dim.ads: Documentation:  number declaration and explicit
	dereference can carry dimension information.
	* sem_dim.adb (Analyze_Dimension_Number_Declaration): New
	procedure, to propagate dimension information from expression
	of declaration to named number, whose type becomes one of the
	dimensioned base types rather than universal real.
	(Analyze_Dimension_Binary_Op):
	a) If one operand is a literal that is the value of a declared
	constant after constant-foloding, use the dimensions of the
	declared constant.
	b) If an operand is a literal that is a contant-folded expression,
	and expander is active, do not report a dimension mismatch if
	literal does not carry them, because dimension matching will
	have been checked previously.
