	* gimple.c (gimple_register_type_1): Do not fiddle with
	main-variant or pointer-to chains.  Delay all fixup to
	uniquify_nodes.

	lto/
	* lto.c (lto_ft_common): Remove pointer-to chain teardown.
	(lto_ft_type): Move main-variant and pointer-to chain building ...
	(uniquify_nodes): ... here.  Compute TYPE_CANONICAL also here,
	in a separate final loop.
