* exp_util.adb (Build_Allocate_Deallocate_Proc): If the
designated type is class-wide and the expression is an unchecked
conversion, preserve the conversion when checking the tag of the
designated object, to prevent spurious semantic errors when the
expression in the conversion has an untagged type (for example
an address attribute).
