	(Set_Slice_Subtype): Explicitly freeze the slice's itype at the point
	where the slice's actions are inserted.
	(Decompose_Expr): Account for possible rewriting of slice bounds
	resulting from side effects suppression caused by the above freezing,
	so that folding of bounds is preserved by such rewriting.
