	* tree-ssa-operands.c (add_vars_for_offset): Clean and speed up.
	(add_vars_for_bitmap): Do not recurse further.  Only add vars
	for pointed-to SFTs.
	(add_virtual_operand): Re-instantiate loop to add operands for
	aliases.  Recurse into MPTs.
	(get_indirect_ref_operands): If we fall back to use a pointers
	SMT, make sure to not prune based on the access offset and size.
