	* exp_aggr.adb (Expand_Array_Aggregate): Do not attempt expansion
	if error already detected.  We may reach this point in spite of
	previous errors when compiling with -gnatq, to force all possible
	errors (this is the usual ACATS mode).

	* checks.adb (Generate_Range_Check): For the case of converting
	a base type with a larger range to a smaller target subtype, only
	use unchecked conversions of bounds in the range check followed
	by conversion in the case where both types are discrete. In other
	cases, convert to the target base type and save in a temporary
	followed by the range check.
	(Convert_And_Check_Range): New procedure factoring code to save
	conversion to a temporary followed by a range check (called two
	places in Generate_Range_Check).
	* exp_ch4.adb (Expand_N_Type_Conversion): Relax previous
	check-in, to generate range checks for conversions between
	any floating-point types rather than limiting it to matching
	base types.
